Using `rust` instead of `rustc cargo` doesn't work in either `systemPackages` or `nix-shell -p`

User's Guide to the Rust Infrastructure
To install the rust compiler and cargo put
rustc
cargo
into the environment.systemPackages or bring them into
scope with nix-shell -p rustc cargo.
For daily builds (beta and nightly) use either rustup from nixpkgs or use the Rust nightlies overlay.
Packaging Rust applications
Rust applications are packaged by using the buildRustPackage helper from rustPlatform:
rustPlatform.buildRustPackage rec {
name = "ripgrep-${version}";
version = "0.4.0";
src = fetchFromGitHub {
owner = "BurntSushi";
repo = "ripgrep";
rev = "${version}";
sha256 = "0y5d1n6hkw85jb3rblcxqas2fp82h3nghssa4xqrhqnz25l799pj";
};
cargoSha256 = "0q68qyl2h6i0qsz82z840myxlnjay8p1w5z7hfyr8fqp7wgwa9cx";
meta = with stdenv.lib; {
description = "A fast line-oriented regex search tool, similar to ag and ack";
homepage = https://github.com/BurntSushi/ripgrep;
license = licenses.unlicense;
maintainers = [ maintainers.tailhook ];
platforms = platforms.all;
};
}
buildRustPackage requires a cargoSha256 attribute which is computed over
all crate sources of this package. Currently it is obtained by inserting a
fake checksum into the expression and building the package once. The correct
checksum can be then take from the failed build.
To install crates with nix there is also an experimental project called nixcrates.
Using the Rust nightlies overlay
Mozilla provides an overlay for nixpkgs to bring a nightly version of Rust into scope. This overlay can also be used to install recent unstable or stable versions of Rust, if desired.
To use this overlay, clone
nixpkgs-mozilla,
and create a symbolic link to the file
rust-overlay.nix
in the ~/.config/nixpkgs/overlays directory.
$ git clone https://github.com/mozilla/nixpkgs-mozilla.git
$ mkdir -p ~/.config/nixpkgs/overlays
$ ln -s $(pwd)/nixpkgs-mozilla/rust-overlay.nix ~/.config/nixpkgs/overlays/rust-overlay.nix
The latest version can be installed with the following command:
$ nix-env -Ai nixos.latest.rustChannels.stable.rust
Or using the attribute with nix-shell:
$ nix-shell -p nixos.latest.rustChannels.stable.rust
To install the beta or nightly channel, "stable" should be substituted by "nightly" or "beta", or use the function provided by this overlay to pull a version based on a build date.
The overlay automatically updates itself as it uses the same source as rustup.
