srid/rust-nix-template

A template Rust project with fully functional and no-frills Nix support, as well as builtin VSCode configuration to get IDE experience without any manual setup (just open in VSCode and accept the suggestions). Based on dream2nix and nix-cargo-integration.

Note: If you are looking for the original template based on this blog post's use of crate2nix, browse from this tag.

Adapting this template

• Run nix develop to have a working shell ready before name change (Workaround for an issue
• Change name in Cargo.toml and flake.nix. Also change description in flake.nix.
• Run cargo generate-lockfile in the nix shell
• There are two CI workflows, and one of them uses Nix which is slower (unless you configure a cache) than the other that is based on rustup. Pick one or the other depending on your trade-offs.

Development (Flakes)

This repo uses Flakes from the get-go, but compat is provided for traditional nix-shell/nix-build as well (see the section below).

# Dev shell
nix develop

# or run via cargo
nix develop -c cargo run

# build
nix build

Development (Legacy Nix)

# Dev shell
nix-shell

# run via cargo
nix-shell --run 'cargo run'

# build
nix-build

There is also a bin/run script which starts 'cargo watch'; it is used by VSCode as well (Ctrl+Shift+B).
