nix-rust-template

A reasonable way to start developing a reproducible Rust project.

This reproducibility is enabled by Nix and Docker.

Features

This is a template repository; everything is customizable, and some helpful defaults are included.

• Default rust extensions:
  • clippy-preview: A collection of lints to catch common mistakes and improve your Rust code
  • rust-src
  • rustc-dev
  • rustfmt: A tool for formatting Rust code according to style guidelines
• Default dev tools:
  • rust-analyzer: Excellent IDE support
  • cargo-watch: Watches over your project's source for changes, and runs Cargo commands when they occur
  • cargo-edit: Extends Cargo to allow you to add, remove, and upgrade dependencies by modifying your Cargo.toml file from the command line
• naersk: Nix support for building cargo crates
• oxalica/rust-overlay: Pure and reproducible overlay for binary distributed rust toolchains

Setup

With Docker

With docker compose (recommended)

docker compose build
docker compose up

Without docker compose

docker build . -t nix-rust-template
docker volume create nix-rust-template-vol
docker run --rm -it -v $PWD:/service nix-rust-template:latest

Without Docker

1. Install nix
2. Install nix flakes

Commands

If you are using Docker, prefix the following with docker compose run --rm app; for example:

docker compose run --rm app nix run .#watch

• nix build: build the package
• nix run or nix run .#app: run the package
• nix run .#watch: watch the package for changes and rerun
• nix develop: enter a reproducible rust shell environment
  • How to watch for changes and rerun:

    cargo watch -w "./src/" -x "run"
