## Summary [summary]: #summary Adds a new syntactical element called an "inline `const`", written as `const { ... }`, which instructs the compiler to execute the contents of the block at compile-time. An inline `const` can be used as an exp...
## Summary [summary]: #summary The RFC proposes a plan to adopt rust-analyzer as Rust's official LSP implementation. The transition to rust-analyzer will take place in a few stages: * **Feedback** -- encourage people to use rust-analyzer an...
## Summary [summary]: #summary We allow destructuring on assignment, as in `let` declarations. For instance, the following are now accepted: ```rust (a, (b.x.y, c)) = (0, (1, 2)); (x, y, .., z) = (1.0, 2.0, 3.0, 4.0, 5.0); [_, f, *baz(), a[...
## Summary [summary]: #summary Deduplicate common dependency and metadata directives amongst a set of workspace crates in Cargo with extensions to the `[workspace]` section in `Cargo.toml`. ## Motivation [motivation]: #motivation Cargo has...
## Summary [summary]: #summary This RFC proposes a policy for managing permissions to the [Rust-Lang GitHub Organization](https://www.github.com/rust-lang) and repositories within this organization. This RFC was written in consultation with...
# Rust 2020 Roadmap - Feature Name: N/A - Start Date: 2020-01-22 - RFC PR: [rust-lang/rfcs#2857](https://github.com/rust-lang/rfcs/pull/2857) - Rust Issue: N/A ## Summary [summary]: #summary Lays out the Rust roadmap for 2020 in pursuit of...
## Summary [summary]: #summary This RFC proposes a new function attribute, `#[instruction_set(set)]` which allows you to declare the instruction set to be used when compiling the function. It also proposes two initial allowed values for the...
Encoders and decoders for common data encodings (base64, bech32, hex)
which avoid data-dependent branching/table lookups and therefore
provide "best effort" constant time. Useful for encoding/decoding
secret values such as cryptographic keys.
## Summary [summary]: #summary This RFC specifies a new syntax for inline assembly which is suitable for eventual stabilization. The initial implementation of this feature will focus on the ARM, x86 and RISC-V architectures. Support for mor...
## Summary [summary]: #summary Change item resolution for generics and trait objects so that a trait bound does not bring its supertraits' items into scope if the subtrait defines an item with this name itself. ## Motivation [motivation]: #...
## Summary [summary]: #summary Deprecate the existing `asm!` macro and provide an identical one called `llvm_asm!`. The feature gate is also renamed from `asm` to `llvm_asm`. Unlike `asm!`, `llvm_asm!` is not intended to ever become stable....
## Summary [summary]: #summary Add the ability to export symbols from executables, not just dylibs, via a new compiler flag: `-C export-executable-symbols`. ## Motivation [motivation]: #motivation Java and C# can't statically link against C...
## Summary [summary]: #summary Cargo should alert developers to upstream dependencies that trigger future-incompatibility warnings. Cargo should list such dependencies even when these warnings have been suppressed (e.g. via cap-lints or `#[...
## Summary [summary]: #summary This RFC proposes to demote the `i686-apple-darwin` rustc target from Tier 1 to Tier 3, and to demote the `armv7-apple-ios`, `armv7s-apple-ios` and `i386-apple-ios` rustc targets from Tier 2 to Tier 3. ## Moti...
## Summary [summary]: #summary To create a [project group] with the purpose of designing subsequent RFCs to extend the language to support inline assembly in Rust code. ## Motivation [motivation]: #motivation In systems programming some tas...
"I’ve said it before and I’ll say it again: as a child of OCaml and C++, Rust currently is the best language for production compiler-shaped things."
