harbor-rs

harbor-rs is reusable Rust cross-compilation and toolchain infrastructure for Nix flakes. It packages the common setup needed for Rust workspaces that target Linux, Windows, and macOS without forcing each project to rebuild the same Nix plumbing.

The library exposes:

• mkToolchain for Rust toolchains with crane
• mkCargoConfig for generated .cargo/config.toml
• mkCross for MinGW and optional osxcross environments
• mkDevShell and mkDevShells for consistent development shells
• mkGpuRenderPin for GPU/driver identity checks in visual snapshot tests
• mkAppImage and mkFlatpakManifest for packaging outputs
• mkAdapter and mkAtticPush for binary cache integration

Start with Installation if you want to consume the flake in another project, or jump to Quick Start for a minimal cross-compiling shell.
