Implementation of Parser::or

Trait Implementations

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

where I: Clone, E: ParseError<I>, F: Parser<I, O, E>, G: Parser<I, O, E>,

fn parse(&mut self, i: I) -> Result<(I, O), Err<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, E2>(self) -> Into<Self, O, O2, E, E2>

where O2: From<O>, E2: From<E>, Self: Sized,

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