fn parse(&mut self, i: I) -> IResult<I, O, E>[−]

A parser takes in input type, and returns a Result containing either the remaining input and the output value, or an error

fn map<G, O2>(self, g: G) -> Map<Self, G, O> where
    G: Fn(O) -> O2,
    Self: Sized, [−]

Maps a function over the result of a parser

fn flat_map<G, H, O2>(self, g: G) -> FlatMap<Self, G, O> where
    G: Fn(O) -> H,
    H: Parser<I, O2, E>,
    Self: Sized, [−]

Creates a second parser from the output of the first one, then apply over the rest of the input

fn and_then<G, O2>(self, g: G) -> AndThen<Self, G, O> where
    G: Parser<O, O2, E>,
    Self: Sized, [−]

Applies a second parser over the output of the first one

fn and<G, O2>(self, g: G) -> And<Self, G> where
    G: Parser<I, O2, E>,
    Self: Sized, [−]

Applies a second parser after the first one, return their results as a tuple

fn or<G>(self, g: G) -> Or<Self, G> where
    G: Parser<I, O, E>,
    Self: Sized, [−]

Applies a second parser over the input if the first one failed

fn into<O2: From<O>, E2: From<E>>(self) -> Into<Self, O, O2, E, E2> where
    Self: Sized, [−]

automatically converts the parser’s output and error values to another type, as long as they implement the From trait
