Make rust.nix accept toolchain options. #640
Conversation
* Remove `languages.rust.packages` and `languages.rust.version` options. * Make nix-community/fenix a hard-requirement for `languages.rust.enable`. * Add ` languages.rust.toolchain` option.

I've added a commit to fix the failing tests, but I think the test will fail again when Rust updates which will require a new Edit: I've pushed another commit which should actually (hopefully) fix the Rust-related errors this time, as well as obviate the need to pass in a specific SHA256 value. |
* This means that it won't work in restricted evaluation mode, but will no longer require passing in a specific SHA256 value. * This should hopefully (actually) fix failing Rust language tests.

It seems like the only failing test related to Rust now is due to the VM running out of storage space (I think the rest of the errors are related to Racket or mesa instead). I'm wondering if maybe enabling cachix for fenix as per these instructions with cachix-action would help alleviate this. @figsoda Are derivation outputs produced by the |
they are not, only outputs that are derivations (without needing a function call) are cached
I'm not sure if this is possible, since |

Closing in favour of #667. |
This makes the Rust option accept toolchain override options in a similar format to rust-toolchain.toml, which should be more familiar to Rust users and allow adding arbitrary components and targets, and is a step forward to addressing #530.
Changes:
languages.rust.packagesandlanguages.rust.versionoptions.languages.rust.enable.languages.rust.toolchainoption.This no longer includes rust-src by default and no longer has pre-commit hooks since the components may no longer be present. How should I handle rust-src and the pre-commit hooks instead?According to the nix-community/fenix maintainer, rust-analyzer will automatically use the rust-src package if it exists. I've pushed a commit which causes the pre-commit hooks to use the rust components if they are added by the user, otherwise it defaults to the ones from nixpkgs.
