Implementation of Parser::flat_map

Trait Implementations

impl<'a, I, O1, O2, E, F: Parser<I, O1, E>, G: Fn(O1) -> H, H: Parser<I, O2, E>> Parser<I, O2, E> for FlatMap<F, G, O1>

fn parse(&mut self, i: I) -> IResult<I, O2, 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: FnMut(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
