How It Works

1. Version Check — Queries crates.io for the latest published version
2. Comparison — Compares with your installed version
3. Installation — Uses cargo-binstall (fast, pre-built binaries) if available, otherwise falls back to cargo install

Notes

• Requires an internet connection to check crates.io
• If cargo-binstall is installed, updates are faster (uses pre-built binaries)
• The update replaces the current rung binary in your PATH
