Installation

Use harbor-rs as a flake input and follow its pinned shared dependencies from your project.

Requirements

Nix with flakes enabled
rust-overlay applied to the pkgs you pass into mkToolchain
nix-direnv, if you use the recommended .envrc
A macOS SDK only if you want Darwin cross-compilation through osxcross

Add the flake input

Pin a published trunk revision. Follow only inputs Harbor actually exposes:

{
  inputs = {
    harbor-rs.url = "git+https://github.com/caniko/harbor-rs.git?ref=trunk&rev=a5b436d24e175042c76d90fc4dbd31e92f7e1721";

    nixpkgs.follows = "harbor-rs/nixpkgs";
    rust-overlay.follows = "harbor-rs/rust-overlay";
    crane.follows = "harbor-rs/crane";
  };
}

Ready-made starting points:

nix flake init -t git+https://github.com/caniko/harbor-rs.git
nix flake init -t git+https://github.com/caniko/harbor-rs.git#bevy

For a working configuration after the input is added, continue to Quick Start.
