RFCs for changes to Rust

I would like to propose that the compiler generates an automatic implementation of **TryFrom** and **Into** for C-style enums. Now I don`t know if they are actually called C-style enums...
#2565 introduced attributes for function parameters. This RFC proposes the logical next step: allowing attributes for function return types. This RFC is less radical than #2602 which proposes that attributes...
Third-party `derive` macros want to be able to use the same direct discriminant access to the `enum` for which they're implementing a trait that the core derive macro does, which...
I think this a good quality of life proposal similar to the [proposal to add a derive Default for enums](https://rust-lang.github.io/rfcs/3107-derive-default-enum.html), not big in scope or magnitude. TLDR: I want to...
Beginning with the 2024 edition, reserve the syntax `#"foo"#`, as a way of future-proofing against future language changes. [Rendered](https://github.com/pitaj/rfcs/blob/unprefixed-strings/text/3593-unprefixed_guarded_strings.md) Note: much of the text of this RFC is directly adapted...
We all know that from inference perspective, all impls are "global" if not excluded with coherence. So this is actually part of the "inference API" of a crate. (But not...
Currently there's a suboptimal interaction between const asserts and const generics. A more general function that is valid for all N cannot call a function that asserts at compile time...
Introduce method `round_to_digits(T: u32)` for `f64` (and `f32`). Same as `f64::round()` except that you can specify how many digits you want to round to. # Example use case: I have...
I'm trying to create a library that rounds float types (f32 and f64) to a specified number of digits by calling on the "round()" function along with some other operations....
