Modernising the libc Crate
The libc crate has been a core part of Rust since its early days, making breaking changes increasingly difficult over time. Redundant and legacy code...
Add safety contracts
There is ongoing work to instrument the Rust standard library with safety contracts. Based on a discussion by the Formal Verification Working Group...
Bootstrap of rustc with rustc_codegen_gcc
Currently, the new, experimental GCC based compiler backend for Rust(`rustc_codegeng_gcc`) is not able to build the Rust compiler. The goal of this...
Make Rustup Concurrent
Rustup is the official toolchain installer and version manager for the Rust programming language. The current implementation of Rustup processes...
Prototype an alternative architecture for cargo fix using cargo check
The current implementation of cargo fix is quite slow and makes extra calls to rustc slowing down the process. A simplified architecture would also...
Distributed and resource-efficient verification
Reduce CI time in verify-rust-std repo by offloading proof verification to multiple Github Runner machines to run verification in parallel, and more...
Make cargo-semver-checks faster
cargo-semver-checks is a development tool that allows rust libraries to check whether a release breaks semver by running lints on the API. For...
Mapping the Maze of Rust's UI Test Suite with Established Continuous Integration Practices
Despite `tests/ui`'s usefulness to maintainers, it acts as a barrier to new contributors - with how expansive it is, major pull requests can break...
Improve Wild linker test suites
This project aims to enhance the testing of the Wild linker by leveraging existing linker test suites, providing strong support for its development....
Parallel Macro Expansion
A lot of work has been done to parallelize the Rust compiler frontend, with notable success in code generation and some post-HIR lowering stages....
Extend behavioural testing of std::arch intrinsics
Rust's std::arch module houses vendor-specific intrinsics (low-level functions that typically correspond to single machine instructions) which are...
Prepare stable_mir crate for publishing
StableMIR aims to provide a stable Rust compiler interface via a stable_mir crate on crates.io, shielding external tools from internal changes....
Cargo: Build script delegation
This project aims to overcome the limitations of the current Build Script system by allowing multiple, well-organised build scripts, that are...
New proc-macro Server API for Rust-Analyzer
Currently, Rust-analyzer expands procedural macros using a client/server architecture, where a separate proc-macro server process loads and executes...
ABI/Layout handling for the automatic differentiation feature
The integration of automatic differentiation (autodiff) into the Rust compiler via Enzyme faces challenges due to ABI adjustments that alter function...
Implement merge functionality in bors
Various Rust repositories under the rust-lang organization use a merge queue bot, bors, for testing and merging pull requests. This project aims to...
Improve bootstrap
This project aims to enhance the testability of Bootstrap and make it faster, the Rust build system, by improving its architecture, refining its...
Enable Witness Generation in cargo-semver-checks
The crate cargo-semver-checks provides feedback to user based on what possible breaking changes they may have made, which as per semantic versioning...
Prototype Cargo Plumbing Commands
This project prototypes a new set of Cargo plumbing commands, aligned with Rust’s 2025H1 project goals. Plumbing commands are lower-level, less...
