Cargo is designed to be extensible with new subcommands without having to modify Cargo itself. This is achieved by translating a cargo invocation of the form cargo (?<command>[^ ]+) into an invocation of an external tool cargo-${command} that then needs to be present in the ~/.cargo/bin/ or one of the user's $PATH directories.

Below is a list of known community-developed subcommands. Please add your own if it's intended and ready for general use.
