Struct som_parser_core::Or

pub struct Or<A, B> { /* private fields */ }

Tries to apply the first parser, if it fails, it tries to apply the second parser.

Trait Implementations

impl<T, A, B, I> Parser<T, I> for Or<A, B>

where I: Clone, A: Parser<T, I>, B: Parser<T, I>,

fn parse(&mut self, input: I) -> Option<(T, I)>

Applies the parser on some input.

fn and<U, P: Parser<U, I>>(self, parser: P) -> And<Self, P>

Sequences two parsers, one after the other, collecting both results.

fn or<P: Parser<T, I>>(self, parser: P) -> Or<Self, P>

Tries to apply the first parser, if it fails, it tries to apply the second parser.

fn map<F: Fn(T) -> U, U>(self, func: F) -> Map<Self, F, T>

Maps a function over the output value of the parser.

fn and_left<P: Parser<U, I>, U>(self, parser: P) -> AndLeft<Self, P, U>

Sequences two parsers, one after the other, but discards the output of the second one.

fn and_right<P: Parser<U, I>, U>(self, parser: P) -> AndRight<Self, P, T>

Sequences two parsers, one after the other, but discards the output of the first one.
