For example: + +```json +{ + "key": "ctrl+alt+d", + "command": "rust-analyzer.openDocs", + "when": "inRustProject" +} +``` + +More about `when` clause contexts +[here](https://code.visualstudio.com/docs/getstarted/keybindings#_when-clause-contexts). + +### Setting runnable environment variables + +You can use "rust-analyzer.runnables.extraEnv" setting to define +runnable environment-specific substitution variables. The simplest way +for all runnables in a bunch: + +```json +"rust-analyzer.runnables.extraEnv": { + "RUN_SLOW_TESTS": "1" +} +``` + +Or it is possible to specify vars more granularly: + +```json +"rust-analyzer.runnables.extraEnv": [ + { + // "mask": null, // null mask means that this rule will be applied for all runnables + "env": { + "APP_ID": "1", + "APP_DATA": "asdf" + } + }, + { + "mask": "test_name", + "env": { + "APP_ID": "2", // overwrites only APP_ID + } + } +] +``` + +You can use any valid regular expression as a mask. Also note that a +full runnable name is something like **run bin\_or\_example\_name**, +**test some::mod::test\_name** or **test-mod some::mod**, so it is +possible to distinguish binaries, single tests, and test modules with +this masks: `"^run"`, `"^test "` (the trailing space matters!), and +`"^test-mod"` respectively. + +If needed, you can set different values for different platforms: + +```json +"rust-analyzer.runnables.extraEnv": [ + { + "platform": "win32", // windows only + "env": { + "APP_DATA": "windows specific data" + } + }, + { + "platform": ["linux"], + "env": { + "APP_DATA": "linux data", + } + }, + { // for all platforms + "env": { + "APP_COMMON_DATA": "xxx", + } + } +] +``` + +### Compiler feedback from external commands + +Instead of relying on the built-in `cargo check`, you can configure Code +to run a command in the background and use the `$rustc-watch` problem +matcher to generate inline error markers from its output. + +To do this you need to create a new [VS Code +Task](https://code.visualstudio.com/docs/editor/tasks) and set +`"rust-analyzer.checkOnSave": false` in preferences. + +For example, if you want to run +[`cargo watch`](https://crates.io/crates/cargo-watch) instead, you might +add the following to `.vscode/tasks.json`: + +```json +{ + "label": "Watch", + "group": "build", + "type": "shell", + "command": "cargo watch", + "problemMatcher": "$rustc-watch", + "isBackground": true +} +``` + +### Live Share + +VS Code Live Share has partial support for rust-analyzer. + +Live Share *requires* the official Microsoft build of VS Code, OSS +builds will not work correctly. + +The host’s rust-analyzer instance will be shared with all guests joining +the session.

If a function +takes arguments, the cursor is positioned inside the parenthesis. + +There are postfix completions, which can be triggered by typing something like +`foo().if`.

wildcards that will match any expression, type, path, pattern or item. +The syntax for a structural search replace command is `<search_pattern> ==>> <replace_pattern>`. +A `$<name>` placeholder in the search pattern will match any AST node and `$<name>` will reference it in the replacement. +Within a macro call, a placeholder will match up until whatever token follows the placeholder. + +All paths in both the search pattern and the replacement template must resolve in the context +in which this command is invoked. Paths in the search pattern will then match the code if they +resolve to the same item, even if they're written differently. For example if we invoke the +command in the module `foo` with a pattern of `Bar`, then code in the parent module that refers +to `foo::Bar` will match. + +Paths in the replacement template will be rendered appropriately for the context in which the +replacement occurs. For example if our replacement template is `foo::Bar` and we match some +code in the `foo` module, we'll insert just `Bar`. + +Inherent method calls should generally be written in UFCS form. e.g. `foo::Bar::baz($s, $a)` will +match `$s.baz($a)`, provided the method call `baz` resolves to the method `foo::Bar::baz`. When a +placeholder is the receiver of a method call in the search pattern (e.g. `$s.foo()`), but not in +the replacement template (e.g. `bar($s)`), then *, & and &mut will be added as needed to mirror +whatever autoderef and autoref was happening implicitly in the matched code. + +The scope of the search / replace will be restricted to the current selection if any, otherwise +it will apply to the whole workspace. + +Placeholders may be given constraints by writing them as `${<name>:<constraint1>:<constraint2>...}`. + +Supported constraints: + +| Constraint | Restricts placeholder | +|---------------|------------------------| +| kind(literal) | Is a literal (e.g. `42` or `"forty two"`) | +| not(a) | Negates the constraint `a` | + +Available via the command `rust-analyzer.ssr`. + +```rust +// Using structural search replace command [foo($a, $b) ==>> ($a).foo($b)] + +// BEFORE +String::from(foo(y + 5, z)) + +// AFTER +String::from((y + 5).foo(z)) +``` + +| Editor | Action Name | +|---------|--------------| +| VS Code | **rust-analyzer: Structural Search Replace** | + +Also available as an assist, by writing a comment containing the structural +search and replace rule.

To configure `kak-lsp`, refer to the [configuration +section](https://github.com/kak-lsp/kak-lsp#configuring-kak-lsp) which +is basically about copying the [configuration +file](https://github.com/kak-lsp/kak-lsp/blob/master/kak-lsp.toml) in +the right place (latest versions should use `rust-analyzer` by default). + +Finally, you need to configure Kakoune to talk to `kak-lsp` (see [Usage +section](https://github.com/kak-lsp/kak-lsp#usage)). A basic +configuration will only get you LSP but you can also activate inlay +diagnostics and auto-formatting on save.

-== Installation - -In theory, one should be able to just install the <<rust-analyzer-language-server-binary,`rust-analyzer` binary>> and have it automatically work with any editor. -We are not there yet, so some editor specific setup is required. - -Additionally, rust-analyzer needs the sources of the standard library. -If the source code is not present, rust-analyzer will attempt to install it automatically. - -To add the sources manually, run the following command: - -```bash -$ rustup component add rust-src -``` - -=== Toolchain - -Only the latest stable standard library source is officially supported for use with rust-analyzer. -If you are using an older toolchain or have an override set, rust-analyzer may fail to understand the Rust source. -You will either need to update your toolchain or use an older version of rust-analyzer that is compatible with your toolchain. - -If you are using an override in your project, you can still force rust-analyzer to use the stable toolchain via the environment variable `RUSTUP_TOOLCHAIN`. -For example, with VS Code or coc-rust-analyzer: - -[source,json] ----- -{ "rust-analyzer.server.extraEnv": { "RUSTUP_TOOLCHAIN": "stable" } } ----- - -=== VS Code - -This is the best supported editor at the moment. -The rust-analyzer plugin for VS Code is maintained -https://github.com/rust-lang/rust-analyzer/tree/master/editors/code[in tree]. - -You can install the latest release of the plugin from -https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer[the marketplace]. - -Note that the plugin may cause conflicts with the -https://marketplace.visualstudio.com/items?itemName=rust-lang.rust[previous official Rust plugin]. -The latter is no longer maintained and should be uninstalled. - -The server binary is stored in the extension install directory, which starts with `rust-lang.rust-analyzer-` and is located under: - -* Linux: `~/.vscode/extensions` -* Linux (Remote, such as WSL): `~/.vscode-server/extensions` -* macOS: `~/.vscode/extensions` -* Windows: `%USERPROFILE%\.vscode\extensions` - -As an exception, on NixOS, the extension makes a copy of the server and stores it under `~/.config/Code/User/globalStorage/rust-lang.rust-analyzer`. - -Note that we only support the two most recent versions of VS Code. - -==== Updates - -The extension will be updated automatically as new versions become available. -It will ask your permission to download the matching language server version binary if needed. - -===== Nightly - -We ship nightly releases for VS Code. -To help us out by testing the newest code, you can enable pre-release versions in the Code extension page. - -==== Manual installation - -Alternatively, download a VSIX corresponding to your platform from the -https://github.com/rust-lang/rust-analyzer/releases[releases] page. - -Install the extension with the `Extensions: Install from VSIX` command within VS Code, or from the command line via: -[source] ----- -$ code --install-extension /path/to/rust-analyzer.vsix ----- - -If you are running an unsupported platform, you can install `rust-analyzer-no-server.vsix` and compile or obtain a server binary. -Copy the server anywhere, then add the path to your settings.json, for example: -[source,json] ----- -{ "rust-analyzer.server.path": "~/.local/bin/rust-analyzer-linux" } ----- - -==== Building From Source - -Both the server and the Code plugin can be installed from source: - -[source] ----- -$ git clone https://github.com/rust-lang/rust-analyzer.git && cd rust-analyzer -$ cargo xtask install ----- - -You'll need Cargo, nodejs (matching a supported version of VS Code) and npm for this. - -Note that installing via `xtask install` does not work for VS Code Remote, instead you'll need to install the `.vsix` manually. - -If you're not using Code, you can compile and install only the LSP server: - -[source] ----- -$ cargo xtask install --server ----- - -Make sure that `.cargo/bin` is in `$PATH` and precedes paths where `rust-analyzer` may also be installed. -Specifically, `rustup` includes a proxy called `rust-analyzer`, which can cause problems if you're planning to use a source build or even a downloaded binary. - -=== rust-analyzer Language Server Binary - -Other editors generally require the `rust-analyzer` binary to be in `$PATH`. -You can download pre-built binaries from the https://github.com/rust-lang/rust-analyzer/releases[releases] page. -You will need to uncompress and rename the binary for your platform, e.g. from `rust-analyzer-aarch64-apple-darwin.gz` on Mac OS to `rust-analyzer`, make it executable, then move it into a directory in your `$PATH`. - -On Linux to install the `rust-analyzer` binary into `~/.local/bin`, these commands should work: - -[source,bash] ----- -$ mkdir -p ~/.local/bin -$ curl -L https://github.com/rust-lang/rust-analyzer/releases/latest/download/rust-analyzer-x86_64-unknown-linux-gnu.gz | gunzip -c - > ~/.local/bin/rust-analyzer -$ chmod +x ~/.local/bin/rust-analyzer ----- - -Make sure that `~/.local/bin` is listed in the `$PATH` variable and use the appropriate URL if you're not on a `x86-64` system. - -You don't have to use `~/.local/bin`, any other path like `~/.cargo/bin` or `/usr/local/bin` will work just as well. - -Alternatively, you can install it from source using the command below. -You'll need the latest stable version of the Rust toolchain. - -[source,bash] ----- -$ git clone https://github.com/rust-lang/rust-analyzer.git && cd rust-analyzer -$ cargo xtask install --server ----- - -If your editor can't find the binary even though the binary is on your `$PATH`, the likely explanation is that it doesn't see the same `$PATH` as the shell, see https://github.com/rust-lang/rust-analyzer/issues/1811[this issue]. -On Unix, running the editor from a shell or changing the `.desktop` file to set the environment should help. - -==== rustup - -`rust-analyzer` is available in `rustup`: - -[source,bash] ----- -$ rustup component add rust-analyzer ----- - -==== Arch Linux - -The `rust-analyzer` binary can be installed from the repos or AUR (Arch User Repository): - -- https://www.archlinux.org/packages/extra/x86_64/rust-analyzer/[`rust-analyzer`] (built from latest tagged source) -- https://aur.archlinux.org/packages/rust-analyzer-git[`rust-analyzer-git`] (latest Git version) - -Install it with pacman, for example: - -[source,bash] ----- -$ pacman -S rust-analyzer ----- - -==== Gentoo Linux - -There are two ways to install `rust-analyzer` under Gentoo: - -- when installing `dev-lang/rust` or `dev-lang/rust-bin`, enable the `rust-analyzer` and `rust-src` USE flags -- use the `rust-analyzer` component in `rustup` (see instructions above) - -Note that in both cases, the version installed lags for a couple of months behind the official releases on GitHub. -To obtain a newer one, you can download a binary from GitHub Releases or building from source. - -==== macOS - -The `rust-analyzer` binary can be installed via https://brew.sh/[Homebrew]. - -[source,bash] ----- -$ brew install rust-analyzer ----- - -==== Windows - -It is recommended to install the latest Microsoft Visual C++ Redistributable prior to installation. -Download links can be found -https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist[here]. - -=== VS Code or VSCodium in Flatpak - -Setting up `rust-analyzer` with a Flatpak version of Code is not trivial because of the Flatpak sandbox. -While the sandbox can be disabled for some directories, `/usr/bin` will always be mounted under `/run/host/usr/bin`. -This prevents access to the system's C compiler, a system-wide installation of Rust, or any other libraries you might want to link to. -Some compilers and libraries can be acquired as Flatpak SDKs, such as `org.freedesktop.Sdk.Extension.rust-stable` or `org.freedesktop.Sdk.Extension.llvm15`. - -If you use a Flatpak SDK for Rust, it must be in your `PATH`: - - * install the SDK extensions with `flatpak install org.freedesktop.Sdk.Extension.{llvm15,rust-stable}//23.08` - * enable SDK extensions in the editor with the environment variable `FLATPAK_ENABLE_SDK_EXT=llvm15,rust-stable` (this can be done using flatseal or `flatpak override`) - -If you want to use Flatpak in combination with `rustup`, the following steps might help: - - - both Rust and `rustup` have to be installed using https://rustup.rs. Distro packages _will not_ work. - - you need to launch Code, open a terminal and run `echo $PATH` - - using https://flathub.org/apps/details/com.github.tchx84.Flatseal[Flatseal], you must add an environment variable called `PATH`. - Set its value to the output from above, appending `:~/.cargo/bin`, where `~` is the path to your home directory. - You must replace `~`, as it won't be expanded otherwise. - - while Flatseal is open, you must enable access to "All user files" - -A C compiler should already be available via `org.freedesktop.Sdk`. -Any other tools or libraries you will need to acquire from Flatpak. - -=== Emacs - -Prerequisites: You have installed the <<rust-analyzer-language-server-binary,`rust-analyzer` binary>>. - -To use `rust-analyzer`, you need to install and enable one of the two popular LSP client implementations for Emacs, https://github.com/joaotavora/eglot[Eglot] or https://github.com/emacs-lsp/lsp-mode[LSP Mode]. Both enable `rust-analyzer` by default in rust buffers if it is available. - -==== Eglot - -Eglot is the more minimalistic and lightweight LSP client for Emacs, integrates well with existing Emacs functionality and is built into Emacs starting from release 29. - -After installing Eglot, e.g. via `M-x package-install` (not needed from Emacs 29), you can enable it via the `M-x eglot` command or load it automatically in `rust-mode` via - -[source,emacs-lisp] ----- -(add-hook 'rust-mode-hook 'eglot-ensure) ----- - -To enable clippy, you will need to configure the initialization options to pass the `check.command` setting. - -[source,emacs-lisp] ----- -(add-to-list 'eglot-server-programs - '((rust-ts-mode rust-mode) . - ("rust-analyzer" :initializationOptions (:check (:command "clippy"))))) ----- - -For more detailed instructions and options see the https://joaotavora.github.io/eglot[Eglot manual] (also available from Emacs via `M-x info`) and the -https://github.com/joaotavora/eglot/blob/master/README.md[Eglot readme]. - -Eglot does not support the rust-analyzer extensions to the language-server protocol and does not aim to do so in the future. The https://github.com/nemethf/eglot-x#rust-analyzer-extensions[eglot-x] package adds experimental support for those LSP extensions. - -==== LSP Mode - -LSP-mode is the original LSP-client for emacs. Compared to Eglot it has a larger codebase and supports more features, like LSP protocol extensions. -With extension packages like https://github.com/emacs-lsp/lsp-mode[LSP UI] it offers a lot of visual eyecandy. -Further it integrates well with https://github.com/emacs-lsp/dap-mode[DAP mode] for support of the Debug Adapter Protocol. - -You can install LSP-mode via `M-x package-install` and then run it via the `M-x lsp` command or load it automatically in rust buffers with - -[source,emacs-lisp] ----- -(add-hook 'rust-mode-hook 'lsp-deferred) ----- - -For more information on how to set up LSP mode and its extension package see the instructions in the https://emacs-lsp.github.io/lsp-mode/page/installation[LSP mode manual]. -Also see the https://emacs-lsp.github.io/lsp-mode/page/lsp-rust-analyzer/[rust-analyzer section] for `rust-analyzer` specific options and commands, which you can optionally bind to keys. - -Note the excellent https://robert.kra.hn/posts/2021-02-07_rust-with-emacs/[guide] from https://github.com/rksm[@rksm] on how to set-up Emacs for Rust development with LSP mode and several other packages. - -=== Vim/Neovim - -Prerequisites: You have installed the <<rust-analyzer-language-server-binary,`rust-analyzer` binary>>. -Not needed if the extension can install/update it on its own, coc-rust-analyzer is one example. - -There are several LSP client implementations for Vim or Neovim: - -==== coc-rust-analyzer - -1. Install coc.nvim by following the instructions at - https://github.com/neoclide/coc.nvim[coc.nvim] - (Node.js required) -2. Run `:CocInstall coc-rust-analyzer` to install - https://github.com/fannheyward/coc-rust-analyzer[coc-rust-analyzer], - this extension implements _most_ of the features supported in the VSCode extension: - * automatically install and upgrade stable/nightly releases - * same configurations as VSCode extension, `rust-analyzer.server.path`, `rust-analyzer.cargo.features` etc. - * same commands too, `rust-analyzer.analyzerStatus`, `rust-analyzer.ssr` etc. - * inlay hints for variables and method chaining, _Neovim Only_ - -Note: for code actions, use `coc-codeaction-cursor` and `coc-codeaction-selected`; `coc-codeaction` and `coc-codeaction-line` are unlikely to be useful. - -==== LanguageClient-neovim - -1. Install LanguageClient-neovim by following the instructions - https://github.com/autozimu/LanguageClient-neovim[here] - * The GitHub project wiki has extra tips on configuration - -2.

Others may require you to know a bit more about the interaction with `rust-analyzer`. - -For the later category, it might help to know that the initial configuration is specified as a value of the `initializationOptions` field of the https://microsoft.github.io/language-server-protocol/specifications/specification-current/#initialize[`InitializeParams` message, in the LSP protocol]. -The spec says that the field type is `any?`, but `rust-analyzer` is looking for a JSON object that is constructed using settings from the list below. -Name of the setting, ignoring the `rust-analyzer.` prefix, is used as a path, and value of the setting becomes the JSON property value. - -For example, a very common configuration is to enable proc-macro support, can be achieved by sending this JSON: - -[source,json] ----- -{ - "cargo": { - "buildScripts": { - "enable": true, - }, - }, - "procMacro": { - "enable": true, - } -} ----- - -Please consult your editor's documentation to learn more about how to configure https://microsoft.github.io/language-server-protocol/[LSP servers]. - -To verify which configuration is actually used by `rust-analyzer`, set `RA_LOG` environment variable to `rust_analyzer=info` and look for config-related messages. -Logs should show both the JSON that `rust-analyzer` sees as well as the updated config. - -This is the list of config options `rust-analyzer` supports: - -include::./generated_config.adoc[] - -== Non-Cargo Based Projects - -rust-analyzer does not require Cargo. -However, if you use some other build system, you'll have to describe the structure of your project for rust-analyzer in the `rust-project.json` format: - -[source,TypeScript] ----- -interface JsonProject { - /// Path to the sysroot directory. - /// - /// The sysroot is where rustc looks for the - /// crates that are built-in to rust, such as - /// std. - /// - /// https://doc.rust-lang.org/rustc/command-line-arguments.html#--sysroot-override-the-system-root - /// - /// To see the current value of sysroot, you - /// can query rustc: - /// - /// ``` - /// $ rustc --print sysroot - /// /Users/yourname/.rustup/toolchains/stable-x86_64-apple-darwin - /// ``` - sysroot?: string; - /// Path to the directory with *source code* of - /// sysroot crates. - /// - /// By default, this is `lib/rustlib/src/rust/library` - /// relative to the sysroot. - /// - /// It should point to the directory where std, - /// core, and friends can be found: - /// - /// https://github.com/rust-lang/rust/tree/master/library. - /// - /// If provided, rust-analyzer automatically adds - /// dependencies on sysroot crates.

For any privacy concerns, you should check with their respective developers. - -For `rust-analyzer` developers, `cargo xtask release` uses the GitHub API to put together the release notes. - -== Features - -include::./generated_features.adoc[] - -== Assists (Code Actions) - -Assists, or code actions, are small local refactorings, available in a particular context. -They are usually triggered by a shortcut or by clicking a light bulb icon in the editor. -Cursor position or selection is signified by `┃` character. - -include::./generated_assists.adoc[] - -== Diagnostics - -While most errors and warnings provided by rust-analyzer come from the `cargo check` integration, there's a growing number of diagnostics implemented using rust-analyzer's own analysis. -Some of these diagnostics don't respect `\#[allow]` or `\#[deny]` attributes yet, but can be turned off using the `rust-analyzer.diagnostics.enable`, `rust-analyzer.diagnostics.experimental.enable` or `rust-analyzer.diagnostics.disabled` settings. - -=== Clippy - -To run `cargo clippy` instead of `cargo check`, you can set `"rust-analyzer.check.command": "clippy"`. - -include::./generated_diagnostic.adoc[] - -== Editor Features -=== VS Code - -==== Color configurations - -It is possible to change the foreground/background color and font family/size of inlay hints. -Just add this to your `settings.json`: - -[source,jsonc] ----- -{ - "editor.inlayHints.fontFamily": "Courier New", - "editor.inlayHints.fontSize": 11, - - "workbench.colorCustomizations": { - // Name of the theme you are currently using - "[Default Dark+]": { - "editorInlayHint.foreground": "#868686f0", - "editorInlayHint.background": "#3d3d3d48", - - // Overrides for specific kinds of inlay hints - "editorInlayHint.typeForeground": "#fdb6fdf0", - "editorInlayHint.parameterForeground": "#fdb6fdf0", - } - } -} ----- - -==== Semantic style customizations - -You can customize the look of different semantic elements in the source code. -For example, mutable bindings are underlined by default and you can override this behavior by adding the following section to your `settings.json`: - -[source,jsonc] ----- -{ - "editor.semanticTokenColorCustomizations": { - "rules": { - "*.mutable": { - "fontStyle": "", // underline is the default - }, - } - }, -} ----- - -Most themes doesn't support styling unsafe operations differently yet. You can fix this by adding overrides for the rules `operator.unsafe`, `function.unsafe`, and `method.unsafe`: - -[source,jsonc] ----- -{ - "editor.semanticTokenColorCustomizations": { - "rules": { - "operator.unsafe": "#ff6600", - "function.unsafe": "#ff6600", - "method.unsafe": "#ff6600" - } - }, -} ----- - -In addition to the top-level rules you can specify overrides for specific themes. For example, if you wanted to use a darker text color on a specific light theme, you might write: - -[source,jsonc] ----- -{ - "editor.semanticTokenColorCustomizations": { - "rules": { - "operator.unsafe": "#ff6600" - }, - "[Ayu Light]": { - "rules": { - "operator.unsafe": "#572300" - } - } - }, -} ----- - -Make sure you include the brackets around the theme name. For example, use `"[Ayu Light]"` to customize the theme Ayu Light. - -==== Special `when` clause context for keybindings. -You may use `inRustProject` context to configure keybindings for rust projects only. -For example: - -[source,json] ----- -{ - "key": "ctrl+alt+d", - "command": "rust-analyzer.openDocs", - "when": "inRustProject" -} ----- -More about `when` clause contexts https://code.visualstudio.com/docs/getstarted/keybindings#_when-clause-contexts[here]. - -==== Setting runnable environment variables -You can use "rust-analyzer.runnables.extraEnv" setting to define runnable environment-specific substitution variables. -The simplest way for all runnables in a bunch: -```jsonc -"rust-analyzer.runnables.extraEnv": { - "RUN_SLOW_TESTS": "1" -} -``` - -Or it is possible to specify vars more granularly: -```jsonc -"rust-analyzer.runnables.extraEnv": [ - { - // "mask": null, // null mask means that this rule will be applied for all runnables - "env": { - "APP_ID": "1", - "APP_DATA": "asdf" - } - }, - { - "mask": "test_name", - "env": { - "APP_ID": "2", // overwrites only APP_ID - } - } -] -``` - -You can use any valid regular expression as a mask. -Also note that a full runnable name is something like *run bin_or_example_name*, *test some::mod::test_name* or *test-mod some::mod*, so it is possible to distinguish binaries, single tests, and test modules with this masks: `"^run"`, `"^test "` (the trailing space matters!), and `"^test-mod"` respectively. - -If needed, you can set different values for different platforms: -```jsonc -"rust-analyzer.runnables.extraEnv": [ - { - "platform": "win32", // windows only - "env": { - "APP_DATA": "windows specific data" - } - }, - { - "platform": ["linux"], - "env": { - "APP_DATA": "linux data", - } - }, - { // for all platforms - "env": { - "APP_COMMON_DATA": "xxx", - } - } -] -``` - -==== Compiler feedback from external commands - -Instead of relying on the built-in `cargo check`, you can configure Code to run a command in the background and use the `$rustc-watch` problem matcher to generate inline error markers from its output. - -To do this you need to create a new https://code.visualstudio.com/docs/editor/tasks[VS Code Task] and set `"rust-analyzer.checkOnSave": false` in preferences. - -For example, if you want to run https://crates.io/crates/cargo-watch[`cargo watch`] instead, you might add the following to `.vscode/tasks.json`: - -```json -{ - "label": "Watch", - "group": "build", - "type": "shell", - "command": "cargo watch", - "problemMatcher": "$rustc-watch", - "isBackground": true -} -``` - -==== Live Share - -VS Code Live Share has partial support for rust-analyzer. -
