Trait nom::branch::Alt[−][src]

pub trait Alt<I, O, E> {
    fn choice(&self, input: I) -> IResult<I, O, E>;
}

helper trait for the alt() combinator

this trait is implemented for tuples of up to 21 elements

Required methods

fn choice(&self, input: I) -> IResult<I, O, E>[src]

tests each parser in the tuple and returns the result of the first one that succeeds
