The Rust Embedded Devices Working Group (wg-embedded) Arm Team (t-arm) agreed to listed as maintainers of: * aarch64-unknown-none * aarch64-unknown-none-softfloat * armv7a-none-eabi * armv7r-none-eabi * armv7r-none-eabihf The aarch64-unknown-none* target didn't have a page so I added it. wg-embedded t-arm did not want to take over: * armebv7r-none-eabi * armebv7r-none-eabihf So I gave them their own target page. The current maintainer remains.

Reject invalid literal suffixes in tuple indexing, tuple struct indexing, and struct field name position Tracking issue: rust-lang/rust#60210 Closes rust-lang/rust#60210 ## Summary Bump the ["suffixes on a tuple index are invalid" non-lint pseudo future-incompatibility warning (#60210)][issue-60210][^non-lint] to a **hard error** across all editions, rejecting the remaining carve outs from accidentally accepted invalid suffixes since Rust **1.27**. - We accidentally accepted invalid suffixes in tuple indexing positions in Rust **1.27**. Originally reported at https://github.com/rust-lang/rust/issues/59418. - We tried to hard reject all invalid suffixes in https://github.com/rust-lang/rust/pull/59421, but unfortunately it turns out there were proc macros accidentally relying on it: https://github.com/rust-lang/rust/issues/60138. - We temporarily accepted `{i,u}{32,size}` in https://github.com/rust-lang/rust/pull/60186 (the "*carve outs*") to mitigate *immediate* ecosystem impact, but it came with an FCW warning indicating that we wanted to reject it after a few Rust releases. - Now (1.89.0) is a few Rust releases later (1.35.0), thus I'm proposing to **also reject the carve outs**. - `std::mem::offset_of!` stabilized in Rust **1.77.0** happens to use the same "don't expect suffix" code path which has the carve outs, so it also accepted the carve out suffixes. I'm proposing to **reject this case as well**. ## What specifically breaks? Code that still relied on invalid `{i,u}{32,size}` suffixes being temporarily accepted by rust-lang/rust#60186 as an ecosystem impact mitigation measure (cf. rust-lang/rust#60138). Specifically, the following cases (particularly the construction of these forms in proc macros like reported in rust-lang/rust#60138): ### Position 1: Invalid `{i,u}{32,size}` suffixes in tuple indexing ```rs fn main() { let _x = (42,).0invalid; // Already error, already rejected by #59421 let _x = (42,).0i8; // Already error, not one of the #60186 carve outs. let _x = (42,).0usize; // warning: suffixes on a tuple index are invalid } ``` ### Position 2: Invalid `{i,u}{32,size}` suffixes in tuple struct indexing ```rs fn main() { struct X(i32); let _x = X(42); let _x = _x.0invalid; // Already error, already rejected by #59421 let _x = _x.0i8; // Already error, not one of the #60186 carve outs. let _x = _x.0usize; // warning: suffixes on a tuple index are invalid } ``` ### Position 3: Invalid `{i,u}{32,size}` suffixes in numeric struct field names ```rs fn main() { struct X(i32, i32, i32); let _x = X(1, 2, 3); let _y = X { 0usize: 42, 1: 42, 2: 42 }; // warning: suffixes on a tuple index are invalid match _x { X { 0usize: 1, 1: 2, 2: 3 } => todo!(), // warning: suffixes on a tuple index are invalid _ => {} } } ``` ### Position 4: Invalid `{i,u}{32,size}` suffixes in `std::mem::offset_of!` While investigating the warning, unfortunately I noticed `std::mem::offset_of!` also happens to use the "expect no suffix" code path which had the carve outs. So this was accepted since Rust **1.77.0** with the same FCW: ```rs fn main() { #[repr(C)] pub struct Struct<T>(u8, T); assert_eq!(std::mem::offset_of!(Struct<u32>, 0usize), 0); //~^ WARN suffixes on a tuple index are invalid } ``` ### The above forms in proc macros For instance, constructions like (see tracking issue rust-lang/rust#60210): ```rs let i = 0; quote! { foo.$i } ``` where the user needs to actually write ```rs let i = syn::Index::from(0); quote! { foo.$i } ``` ### Crater results Conducted a crater run (https://github.com/rust-lang/rust/pull/145463#issuecomment-3194920383). - https://github.com/AmlingPalantir/r4/tree/256af3c72f094b298cd442097ef7c571d8001f29: genuine regression; "invalid suffix `usize`" in derive macro. Has a ton of other build warnings, last updated 6 years ago. - Exactly the kind of intended breakage. Minimized down to https://github.com/AmlingPalantir/r4/blob/256af3c72f094b298cd442097ef7c571d8001f29/validates_derive/src/lib.rs#L71-L75, where when interpolation uses `quote`'s `ToTokens` on a `usize` index (i.e. on tuple struct `Tup(())`), the generated suffix becomes `.0usize` (cf. Position 2). - Notified crate author of breakage in https://github.com/AmlingPalantir/r4/issues/1. - Other failures are unrelated or spurious. ## Review remarks - Commits 1-3 expands the test coverage to better reflect the current situation before doing any functional changes. - Commit 4 is an intentional **breaking change**. We bump the non-lint "suffixes on a tuple index are invalid" warning into a hard error. Thus, this will need a crater run and a T-lang FCP. ## Tasks - [x] Run crater to check if anyone is still relying on this being not a hard error. Determine degree of ecosystem breakage. - [x] If degree of breakage seems acceptable, draft nomination report for T-lang for FCP. - [x] Determine hard error on Edition 2024+, or on all editions. ## Accompanying Reference update - https://github.com/rust-lang/reference/pull/1966 [^non-lint]: The FCW was implemented as a *non-lint* warning (meaning it has no associated lint name, and you can't `#![deny(..)]` it) because spans coming from proc macros could not be distinguished from regular field access. This warning was also intentionally impossible to silence. See https://github.com/rust-lang/rust/pull/60186#issuecomment-485581694. [issue-60210]: https://github.com/rust-lang/rust/issues/60210

rename erase_regions to erase_and_anonymize_regions I find it consistently confusing that `erase_regions` does more than replacing regions with `'erased`. it also makes some code look real goofy to be writing manual folders to erase regions with a comment saying "we cant use erase regions" :> or code that re-calls erase_regions on types with regions already erased just to anonymize all the bound regions. r? lcnr idk how i feel about the name being almost twice as long now

mark `format_args_nl!` as `#[doc(hidden)]` The `#[unstable]` attribute of the macro already says: > `format_args_nl` is only for internal language use and is subject to change It does seem plausible to hide it from the `std` docs accordingly.

2025-09-09Rollup merge of #146195 - nixxo:urlencoding-fix, r=ehussStuart Cook-12/+16
fix partial urlencoded link support Hello Rust community. This is my first contribution, hope is useful. While translating in Italian the rust book https://github.com/nixxo/rust-lang-book-it I noticed that the linkchecker tool was failing reporting broken links on some pages even if the link worked properly in the browser. Upon inspection I noticed that mdbook basically urlencoded the links, but not urlencoded the heading IDs resulting in a non-identical anchor/IDs pairing that linkchecker reports as non-valid. looking at the source code for the linkchecker tool I noticed that urlencoding was done by the `small_url_encode` function in a partial way, as the name suggests. Replacing this function with a full urlencoding fixes the issue and the links are properly reported as valid. - added full urlencoding to properly check urlencoded anchor links against non-urlencoded heading IDs - added tests urlecoding provided by https://crates.io/crates/urlencoding

2025-09-07optimization: Don't include ASCII characters in Unicode tablesKarl Meakin-0/+5
The ASCII subset of Unicode is fixed and will never change, so we don't need to generate tables for it with every new Unicode version. This saves a few bytes of static data and speeds up `char::is_control` and `char::is_grapheme_extended` on ASCII inputs. Since the table lookup functions exported from the `unicode` module will give nonsensical errors on ASCII input (and in fact will panic in debug mode), I had to add some private wrapper methods to `char` which check for ASCII-ness first.

Split `run-make` into two {`run-make`,`run-make-cargo`} test suites ## Summary Split `tests/run-make` into two test suites, to make it faster and more convenient for contributors to run run-make tests that do not need in-tree `cargo`. | New test suites | Explanation | | ---------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `tests/run-make` | The "fast path" test suite intended for run-make tests that do not need in-tree `cargo`. These tests may not use `cargo`. | | `tests/run-make-cargo` | The "slow path" test suite that requires checking out `cargo` submodule and building in-tree `cargo`, and thus will have access to in-tree `cargo`. In practice, these constitute a very small portion of the original `run-make` tests. | This PR carries out [MCP 847: Split run-make test suite into slower-building test suite with suitably-staged cargo and faster-building test suite without cargo](https://github.com/rust-lang/compiler-team/issues/847). Fixes rust-lang/rust#135573 (for the tests that do not need in-tree `cargo`). Fixes rust-lang/rust#134109. ## Remarks - I considered if we want to split by in-tree tools previously. However, as discussed rust-lang/rust#134109, in practice `rustdoc` is not very slow to build, but `cargo` takes a good few minutes. So, the partition boundary was determined to be along in-tree `cargo` availability. - The `run-make` tests previously that wanted to use `cargo` cannot just use the bootstrap `cargo`, otherwise they would run into situations where bootstrap `cargo` can significantly diverge from in-tree `cargo` (see https://github.com/rust-lang/rust/pull/130642). --- try-job: aarch64-msvc-1 try-job: test-various try-job: x86_64-gnu-debug try-job: aarch64-gnu-debug try-job: aarch64-apple try-job: dist-various-1
