Crates.nix

A simple wrapper using crates-io-index for nix

If you need a package from crates.io which is not packaged or available in nixpkgs then you can use this

By default this will use the latest version available on crates.io (you can use nix flake update crates-nix to update crates-io-index)

This has two main functions buildCrate and fetchCrate

`buildCrate'

Signature

buildCrate "string" {attrs}

Example

foo = crates.buildCrate "foo" {
    buildInputs = with pkgs; [libxml];
}; 

fetchCrate

Signature

fetchCrate "string" {attrs}

Example

foo-src = crates.fetchCrate "foo" {};

Other Examples

crates = crates-nix.mkLib {inherit pkgs;};
foo = crates.buildCrate "foo" {};
foo-src = crates.fetchCrate "foo" {};
foo-v1 = crates.buildCrate "foo" { version = "1" };

Example

Example flake.nix file

{
  description = "Flake utils demo";
  inputs = {
    flake-utils.url = "github:numtide/flake-utils";
    crates-nix = {
      url = "github:uttarayan21/crates.nix";
      inputs.crates-io-index.follows = "crates-io-index";
    };
    crates-io-index = {
      url = "github:rust-lang/crates.io-index";
      flake = false;
    };
  };

  outputs = {
    self,
    nixpkgs,
    crates-nix,
    flake-utils,
    ...
  }:
    flake-utils.lib.eachDefaultSystem (
      system: let
        pkgs = nixpkgs.legacyPackages.${system};
        crates = crates-nix.mkLib {inherit pkgs;};
      in {
        packages = rec {
          default = ripgrep;
          foo = crates.buildCrate "foo" {
            buildInputs = with pkgs; [libxml];
          }; 
        };
        devShells = pkgs.mkShell {
            packages = [(crates.buildCrate "cargo-with" {})];
        };
      }
    );
