Type Alias Projected 

pub type Projected = Result<Command, Error>;

What every action handler produces. Projection can still fail — an endpoint that is neither on argv nor in the environment, an integer outside its domain range — and those are argument errors, not run failures.

Aliased Type

pub enum Projected {
    Ok(Command),
    Err(Error),
}

Variants

Ok(Command)

Contains the success value

Err(Error)
