Use the Nix C API from Rust.
The development environment and building with Nix are taken care of by nix-cargo-integration (options).
The dependency on Nix is taken care of with the nix-bindings-rust flake-parts module.
Example usage:
{ outputs = inputs@{ self, flake-parts, ... }: flake-parts.lib.mkFlake { inherit inputs; } { imports = [ inputs.nix-cargo-integration.flakeModule inputs.nix-bindings-rust.modules.flake.default ]; perSystem = { config, pkgs, ... }: { # optional: nix-bindings-rust.nixPackage = pkgs.nix; nci.projects."myproject" = { depsDrvConfig = { imports = [ config.nix-bindings-rust.nciBuildConfig ]; }; }; }; }; }The following will open a shell with dependencies, and install pre-commit for automatic formatting.
$ nix developIf the rust-analyzer extension fails, make sure the devShell was loaded into VSCode via Nix Env Selector or direnv.
