where F: Parser<I, O, E>, O2: Default,

fn parse_next(&mut self, input: &mut I) -> PResult<O2, E>

Take tokens from the Stream, turning it into the output

fn parse_peek(&mut self, input: I) -> IResult<I, O, E>

Take tokens from the Stream, turning it into the output

fn by_ref(&mut self) -> ByRef<'_, Self>

where Self: Sized,

Treat &mut Self as a parser

fn value<O2>(self, val: O2) -> Value<Self, I, O, O2, E>

where Self: Sized, O2: Clone,

Produce the provided value
