cmse: test returning `MaybeUninit<T>` tracking issue: https://github.com/rust-lang/rust/issues/81391 tracking issue: https://github.com/rust-lang/rust/issues/75835 Some tests from https://github.com/rust-lang/rust/pull/147697 that already work and are useful. Extracting them shrinks that (currently blocked) PR. The code in `tests/ui/cmse-nonsecure/cmse-nonsecure-call/return-via-stack.rs` checks that `MaybeUninit<T>` is considered abi-compatible with `T`. The code in `tests/ui/cmse-nonsecure/cmse-nonsecure-entry/params-via-stack.rs` really only tests that no errors/warnings are emitted. r? davidtwco
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
