About:
Cargo-watch is a utility that monitors your Rust project's source files for changes and automatically triggers cargo commands like check, build, or test. It provides rapid feedback during development by eliminating the need for manual recompilation. This tool significantly speeds up the development workflow for Rust developers.
Key Features:
  • Instantly re-runs cargo commands on file changes
  • Highly configurable with ignore patterns and custom commands
  • Cross-platform support (Linux, macOS, Windows)
  • Low resource footprint
Use Cases:
  • Automatically recompiling and running tests during Rust development
  • Linting code on save to catch errors early
  • Rebuilding documentation when source files change
Alternatives:
  • system file watcher – Requires writing custom shell scripts, whereas cargo-watch is a pre-packaged solution
  • entr – Generic file watcher, whereas cargo-watch is specifically optimized for the Cargo ecosystem
