Function argonaut::parse [−] [src]

pub fn parse<'def, 'tar, T, P: Into<String>>(
    program: P, 
    args: &[T], 
    definitions: Vec<ArgDef<'def, 'tar>>
) -> Result<Option<i32>, ParseError<'def>> where
    T: Borrow<str>,

Parses the given arguments and updates the defined variables with them.

Errors are handled like this: - Invalid argument definitions (logic error): Panic. - Parse failed: Print usage and prevent the error from propagating. - Interrupt or sub parse failed: Just passed along.
