If the target we're generating code for is msvc, then we do two main things differently: we generate type names in a C++ style instead of a Rust style and we generate debuginfo for enums differently. I've refactored the code so that there is one function (`cpp_like_debuginfo`) which determines if we should use the C++ style of naming types and other debuginfo generation or the regular Rust one.
Previously suggested in rust-lang/rfcs#2854. It makes sense to have this since `char` implements `From<u8>`. Likewise `u32`, `u64`, and `u128` (since rust-lang#79502) implement `From<char>`.
Implement `TryFrom<char>` for `u8` Previously suggested in rust-lang/rfcs#2854. It makes sense to have this since `char` implements `From<u8>`. Likewise `u32`, `u64`, and `u128` (since rust-lang#79502) implement `From<char>`.
…erister Remove &self from PrintState::to_string The point of `PrintState::to_string` is to create a `State` and evaluate the caller's closure on it: https://github.com/rust-lang/rust/blob/e9fbe79292783972a222afd270db3f77c0b4f3c8/compiler/rustc_ast_pretty/src/pprust/state.rs#L868-L872 Making the caller *also* construct and pass in a `State`, which is then ignored, was confusing.
…svc_check, r=michaelwoerister Consolidate checking for msvc when generating debuginfo If the target we're generating code for is msvc, then we do two main things differently: we generate type names in a C++ style instead of a Rust style and we generate debuginfo for enums differently. I've refactored the code so that there is one function (`cpp_like_debuginfo`) which determines if we should use the C++ style of naming types and other debuginfo generation or the regular Rust one. r? ``@michaelwoerister`` This PR is not urgent so please don't let it interrupt your holidays! 🎄 🎁
…ant-count, r=the8472 Add note about non_exhaustive to variant_count Since `variant_count` isn't returning something opaque, I thought it makes sense to explicitly call out that its return value may change for some enums. cc rust-lang#73662
…htriplett
Add some missing `#[must_use]` to some `f{32,64}` operations
This PR adds `#[must_use]` to the following methods:
- `f32::recip`
- `f32::max`
- `f32::min`
- `f32::maximum`
- `f32::minimum`
and their equivalents in `f64`.
These methods all produce a new value without modifying the original and so are pointless to call without using the result.
…-inline-style, r=jsha Create CSS class instead of using inline style for search results I saw this change in the update you proposed in rust-lang#92404. :) r? ``@jsha``
…allelism, r=joshtriplett Implement stabilization of `#[feature(available_parallelism)]` Stabilized in rust-lang#74479 (comment). Closes rust-lang#74479. Thanks! cc/ ``@rust-lang/libs-api``
