Trait conch_runtime::env::ShiftArgumentsEnvironment

pub trait ShiftArgumentsEnvironment {
    fn shift_args(&mut self, amt: usize);
}

An interface for shifting positional shell and function arguments.

Required Methods

fn shift_args(&mut self, amt: usize)

Shift parameters such that the positional parameter n will hold the value of the positional parameter n + amt.

If amt == 0, then no change to the positional parameters should be made.
