An executable command-like object.

Builtins and user functions are all its instances.

It must be cheaply clone-able.

Required Methods

fn as_any(&self) -> &dyn Any

fn exec<'fut>( &'fut self, ctx: &'fut mut ExecContext<'_>, args: &'fut [String], ) -> Pin<Box<dyn Future<Output = ()> + 'fut>>

Provided Methods

fn description(&self) -> Option<&str>
