A pure and reproducible Nix overlay that packages binary-distributed Rust toolchains, including stable, beta, and nightly versions. It provides both classic overlay and Nix Flake interfaces, with pre-fetched component hashes for pure evaluation and daily auto-updated hashes via GitHub Actions.

Use cases

• install a specific rust toolchain version reproducibly with nix
• pin rust nightly in a nix flake for a project
• replace nixpkgs-mozilla rust overlay
• set up cross-compilation rust toolchains with nix
• provide rust toolchain in a nix shell dev environment
• use rust in NixOS configuration without rustup

When to choose

• you use Nix or NixOS and want reproducible, pure rust toolchain installs
• you need pinned nightly or specific rust versions in flakes
• you want to avoid rustup and manage rust via nix
• you need cross-compilation toolchains managed declaratively

When to avoid

• you don't use Nix and just want a simple rust install (use rustup)
• you need platforms other than x86_64-linux with guaranteed support
• you need very old nightly versions (only available via old snapshot tags)
