Implementation of Parser::or

Trait Implementations§

source§

impl<'a, I: Clone, O, E: ParseError<I>, F: Parser<I, O, E>, G: Parser<I, O, E>> Parser<I, O, E> for Or<F, G>

source§

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
source§

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
source§

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
source§

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
source§

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
source§

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
source§

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
