Closing the Nix Gap: From Environments to Packaged Applications for Rust

  • devenv simplifies Rust development with `languages.rust.enable`, providing tools like `cargo`, `rustc`, and `rust-analyzer` without Nix packaging knowledge.
  • For deployment, devenv offers `languages.rust.import` using `crate2nix`, eliminating the need to choose between tools like `crate2nix`, `cargo2nix`, `naersk`, or `crane`.
  • A unified workflow is provided for all languages: enable development tools with `languages.<lang>.enable` and package with `languages.<lang>.import`.
  • Example configuration shows enabling Rust, Python, and Go, then importing applications for packaging.
  • `languages.rust.import` generates Nix expressions from `Cargo.toml` and `Cargo.lock`, streamlining the packaging process.
  • Similar interfaces are being developed for other languages, like Python with `uv2nix` in PR #2115.
  • Community feedback is encouraged via Discord.
