Trait Implementations

impl<'a, P: Clone, O1, O2, F: Clone> Clone for Map<'a, P, O1, O2, F>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, P, O1, O2, F> Parser<&'a str, (O2, Vec<Remark, Global>), VerboseError<&'a str>> for Map<'a, P, O1, O2, F> where
    P: EsprParser<'a, O1>,
    F: Fn(O1) -> O2, 

fn parse(&mut self, input: &'a str) -> ParseResult<'a, O2>

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, 

Maps a function over the result of a parser

fn flat_map<G, H, O2>(self, g: G) -> FlatMap<Self, G, O> where
    H: Parser<I, O2, E>,
    G: FnMut(O) -> H, 

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>, 

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>, 

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>, 

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

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

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