If a binary in your `$PATH` is named `cargo-something`, you can +run it as if it was a Cargo subcommand by running `cargo something`. Custom +commands like this are also listed when you run `cargo --list`. Being able to +use `cargo install` to install extensions and then run them just like the +built-in Cargo tools is a super convenient benefit of Cargo’s design! + +## Summary + +Sharing code with Cargo and [crates.io](https://crates.io/)<!-- ignore --> is +part of what makes the Rust ecosystem useful for many different tasks. Rust’s +standard library is small and stable, but crates are easy to share, use, and +improve on a timeline different from that of the language. Don’t be shy about +sharing code that’s useful to you on [crates.io](https://crates.io/)<!-- ignore +-->; it’s likely that it will be useful to someone else as well! |
