[Feature Request:] Overriding the stdenv not yet possible

[573]

Describe the bug Currently it is not easily possible to override the stdenv, i. e. to compile to certain targets in rust / cargo.

To reproduce See sscce for this issue.

Version

devenv: 0.6.2

We're getting closer to fixing this, I'm not sure if overriding makes sense for the whole devenv but rather than parts of it?

[domenkozar]

For Rust see #900

Otherwise I'd suggest we add an option to devenv.yaml:

stdenv: pkgs.swift.stdenv

Would that work for your use case?

900 looks like what is missing, the devenv.yaml option could be feasible from flakes as well then further up the road, so yeah, this would be a nice addition.

my use case would be stdenv = pkgs.stdenvAdapters.useMoldLinker pkgs.stdenv;

        rustVersion = pkgs.rust-bin.fromRustupToolchainFile ./rust-toolchain;

        stdenv = pkgs.stdenvAdapters.useMoldLinker pkgs.stdenv;

        rustPlatform = (pkgs.makeRustPlatform {
          cargo = rustVersion;
          rustc = rustVersion;
          inherit stdenv;
        });

Can you try https://github.com/cachix/devenv/pull/1092 and tell me if that works for you as expected?

Tried and worked. Thanks all for the work !
