Trait Implementations
impl<I, O, S, P> Parser for Choice<S, P> where I: Stream, S: AsMut<[P]>, P: Parser<Input=I, Output=O>
[src]
type Input = I
A type implementing the Stream
trait which is the specific type that is parsed. Read more
type Output = O
The type which is returned when the parsing is successful.
fn parse_state(&mut self, input: State<I>) -> ParseResult<O, I>
Parses using the state input
by calling Stream::uncons one or more times On success returns Ok((value, new_state))
on failure it returns Err(error)
