Trait Implementations

impl<'a, I: ?Sized + Sequence, O1, O2, O3, O4, E: ParserError, P1, T1, P2, T2, P3, T3, P4, T4> Parser<'a, I, (O1, O2, O3, O4), E, SeqAlt4<T1, T2, T3, T4>> for Permutation<(P1, P2, P3, P4)>

where P1: Parser<'a, I, O1, E, T1>, P2: Parser<'a, I, O2, E, T2>, P3: Parser<'a, I, O3, E, T3>, P4: Parser<'a, I, O4, E, T4>,

fn fab(&self, input: &mut &'a I) -> Result<(O1, O2, O3, O4), E>

Parses the input. This method advances the input reference to the remaining unparsed input. The method is named “fab” instead of “parse” to avoid conflicts with the “parse” method of &str.

fn fab_value<V: Clone>(self, value: V) -> Value<Self, V, I, O, E>

where Self: Sized,

Returns a parser that replaces the output of the underlying parser with V.

fn fab_map<F>(self, func: F) -> ParserMap<Self, I, O, E, F>

where Self: Sized,

This creates a Map parser that applies the function to the output of the underlying parser.

fn fab_try_map<F>(self, func: F) -> ParserTryMap<Self, I, O, E, F>

where Self: Sized,

This parser first maps the input, and if the result is Option::Some or Result::Ok, it unwraps the input. Othewise, the parser fails.

fn fab_repeat(self) -> Repeat<Self, I, O, E, fn(&mut Vec<O>, O), Vec<O>>

where Self: Sized, O: Clone,

Repeats the underlying parser, returning the results in a Vec. This parser will accept any number of repetitions, including 0.
