These features operate by extending the `#[doc]` attribute, and thus can be caught by the compiler and enabled with a `#![feature(...)]` attribute in your crate. -### `#[doc(cfg)]`: Recording what platforms or features are required for code to be present - - * Tracking issue: [#43781](https://github.com/rust-lang/rust/issues/43781) - -You can use `#[doc(cfg(...))]` to tell Rustdoc exactly which platform items appear on. -This has two effects: - -1. doctests will only run on the appropriate platforms, and -2. When Rustdoc renders documentation for that item, it will be accompanied by a banner explaining - that the item is only available on certain platforms. - -`#[doc(cfg)]` is intended to be used alongside [`#[cfg(doc)]`][cfg-doc]. -For example, `#[cfg(any(windows, doc))]` will preserve the item either on Windows or during the -documentation process. Then, adding a new attribute `#[doc(cfg(windows))]` will tell Rustdoc that -the item is supposed to be used on Windows. For example: - -```rust -#![feature(doc_cfg)] - -/// Token struct that can only be used on Windows. -#[cfg(any(windows, doc))] -#[doc(cfg(windows))] -pub struct WindowsToken; - -/// Token struct that can only be used on Unix. -#[cfg(any(unix, doc))] -#[doc(cfg(unix))] -pub struct UnixToken; - -/// Token struct that is only available with the `serde` feature -#[cfg(feature = "serde")] -#[doc(cfg(feature = "serde"))] -#[derive(serde::Deserialize)] -pub struct SerdeToken; -``` - -In this sample, the tokens will only appear on their respective platforms, but they will both appear -in documentation. - -`#[doc(cfg(...))]` was introduced to be used by the standard library and currently requires the -`#![feature(doc_cfg)]` feature gate. For more information, see [its chapter in the Unstable -Book][unstable-doc-cfg] and [its tracking issue][issue-doc-cfg]. - -### `doc_auto_cfg`: Automatically generate `#[doc(cfg)]` - - * Tracking issue: [#43781](https://github.com/rust-lang/rust/issues/43781) - -`doc_auto_cfg` is an extension to the `#[doc(cfg)]` feature. With it, you don't need to add -`#[doc(cfg(...)]` anymore unless you want to override the default behaviour. So if we take the -previous source code: - -```rust -#![feature(doc_auto_cfg)] - -/// Token struct that can only be used on Windows. -#[cfg(any(windows, doc))] -pub struct WindowsToken; - -/// Token struct that can only be used on Unix. -#[cfg(any(unix, doc))] -pub struct UnixToken; - -/// Token struct that is only available with the `serde` feature -#[cfg(feature = "serde")] -#[derive(serde::Deserialize)] -pub struct SerdeToken; -``` - -It'll render almost the same, the difference being that `doc` will also be displayed.
