System Documentation

What problem does it solve?

cargo2nix helps Rust projects achieve reproducible builds by generating Cargo.nix files that describe per-crate derivations, enabling fine-grained caching and flexible toolchain control.

Core Features & Use Cases

  • Per-crate derivations for selective rebuilding and sharing dependencies across projects.
  • Workspace and multi-binary support with cross-compilation and development shells.
  • Easy integration with Flakes and cargo workflows to keep Cargo.nix in sync with Cargo.lock.

Quick Start

  • Generate Cargo.nix for your project with: nix run github:cargo2nix/cargo2nix
  • Update after changing Cargo.lock: cargo update; nix run github:cargo2nix/cargo2nix; git add Cargo.lock Cargo.nix
