RFCs for changes to Rust
We already allow derive macros and traits to share the same name, so that library users only need to `use` once: ```rust use my_crate::MyTrait; #[derive(MyTrait)] struct MyStruct { // ......
issue for this RFC [rust-lang/rust#134475](https://github.com/rust-lang/rust/issues/134475) This RFC proposes checking for `T: Sized` in required trait methods (which do not check for some reason) which will be a future compatibility lint...
This has definitely come up in the past, but I think it's worth at least having a response to it. To make a bold claim: Rust can no longer be...

This RFC introduce `DerefInto` and `DerefMutInto`, supertraits of [`Deref`](https://doc.rust-lang.org/std/ops/trait.Deref.html) / [`DerefMut`](https://doc.rust-lang.org/std/ops/trait.DerefMut.html) that return targets by value, enabling ergonomic RAII access for types like RefCell, Mutex, and RwLock.

This RFC was in large part drafted in May 2025, shortly after my Rust All Hands talk, "Futile Feature Gates". There were about 25 people in that room; I want...
While Rust's pre-built standard library has proven itself sufficient for the majority of use cases, there are a handful of use cases that are not well supported: 1. Rebuilding the...
Add a new Cargo configuration option, `build-std = "always|never"`, which will unconditionally rebuild standard library dependencies. The set of standard library dependencies can optionally be customised with a new `build-std-crates`...
Allow users to add explicit dependencies on standard library crates in the `Cargo.toml`. This enables Cargo to determine which standard library crates are required by the crate graph without `build-std-crates`...
