This is just a lint, right? I don't think we need a crater run to ward off ecosystem breakage for new lints, especially on one that's so niche. |
If you look at the diff it introduces both warnings and errors in different places. |

Errors were previously emitted on So this adds both a lint, but also errors that had previously accidentally been left out. |

…thewjasper Lint ignored `#[inline]` on function prototypes Fixes rust-lang#51280. - Adds a `unused_attribute` lint for `#[inline]` on function prototypes. - As a consequence, foreign items, impl items and trait items now have their attributes checked, which could cause some code to no longer compile (it was previously erroneously ignored).

Version 1.40.0 (2019-12-19) =========================== Language -------- - [You can now use tuple `struct`s and tuple `enum` variant's constructors in `const` contexts.][65188] e.g. ```rust pub struct Point(i32, i32); const ORIGIN: Point = { let constructor = Point; constructor(0, 0) }; ``` - [You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to indicate that there may be variants or fields added in the future.][64639] For example this requires adding a wild-card branch (`_ => {}`) to any match statements on a non-exhaustive `enum`. [(RFC 2008)] - [You can now use function-like procedural macros in `extern` blocks and in type positions.][63931] e.g. `type Generated = macro!();` - [Function-like and attribute procedural macros can now emit `macro_rules!` items, so you can now have your macros generate macros.][64035] - [The `meta` pattern matcher in `macro_rules!` now correctly matches the modern attribute syntax.][63674] For example `(#[$m:meta])` now matches `#[attr]`, `#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`. Compiler -------- - [Added tier 3 support\* for the `thumbv7neon-unknown-linux-musleabihf` target.][66103] - [Added tier 3 support for the `aarch64-unknown-none-softfloat` target.][64589] - [Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and `mips64el-unknown-linux-muslabi64` targets.][65843] \* Refer to Rust's [platform support page][forge-platform-support] for more information on Rust's tiered platform support. Libraries --------- - [The `is_power_of_two` method on unsigned numeric types is now a `const` function.][65092] Stabilized APIs --------------- - [`BTreeMap::get_key_value`] - [`HashMap::get_key_value`] - [`Option::as_deref_mut`] - [`Option::as_deref`] - [`Option::flatten`] - [`UdpSocket::peer_addr`] - [`f32::to_be_bytes`] - [`f32::to_le_bytes`] - [`f32::to_ne_bytes`] - [`f64::to_be_bytes`] - [`f64::to_le_bytes`] - [`f64::to_ne_bytes`] - [`f32::from_be_bytes`] - [`f32::from_le_bytes`] - [`f32::from_ne_bytes`] - [`f64::from_be_bytes`] - [`f64::from_le_bytes`] - [`f64::from_ne_bytes`] - [`mem::take`] - [`slice::repeat`] - [`todo!`] Cargo ----- - [Cargo will now always display warnings, rather than only on fresh builds.][cargo/7450] - [Feature flags (except `--all-features`) passed to a virtual workspace will now produce an error.][cargo/7507] Previously these flags were ignored. - [You can now publish `dev-dependencies` without including a `version`.][cargo/7333] Misc ---- - [You can now specify the `#[cfg(doctest)]` attribute to include an item only when running documentation tests with `rustdoc`.][63803] Compatibility Notes ------------------- - [As previously announced, any previous NLL warnings in the 2015 edition are now hard errors.][64221] - [The `include!` macro will now warn if it failed to include the entire file.][64284] The `include!` macro unintentionally only includes the first _expression_ in a file, and this can be unintuitive. This will become either a hard error in a future release, or the behavior may be fixed to include all expressions as expected. - [Using `#[inline]` on function prototypes and consts now emits a warning under `unused_attribute` lint.][65294] Using `#[inline]` anywhere else inside traits or `extern` blocks now correctly emits a hard error.
