## 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 Read more

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 Read more
