Stage 2.6: Cargo Subcommands

cargo subcommands are an option to add additional commands which are developed by the community to customize your developing experience.

To install a cargo subcommand, you simply run: cargo install name-of-subcommand

For example to install the cargo-watch subcommand, you simply run: cargo install cargo-watch.
To see all available option for this new cargo subcommand, just run: cargo watch --help

cargo watch is a pretty useful command to run or test your code everytime something has changed. It can be used like: cargo watch -x run. This would execute cargo run whenever it detects a change.

There are other useful commands like cargo-edit which adds multiple subcommands (cargo add, cargo rm and cargo upgrade) to handle dependencies via CLI commands.
