Trait Run 

pub trait Run {
    type Output;

    // Required method
    fn run(self) -> Self::Output;
}

A command that can be carried out with nothing but what it parsed.

The output is the implementation’s own: Result<(), E> for a CLI whose commands can fail, () for one whose commands cannot, ExitCode for one that decides its own status. A generated dispatcher takes its output from the first command it routes to and requires the rest to agree, since a match has one type.

Required Associated Types

Required Methods

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety".
