Struct peruse::parsers::MapParser

pub struct MapParser<I: ?Sized, P: Parser<I = I>, T> { /* fields omitted */ }

A Parser that uses a closure to map the result of another parser

Trait Implementations

impl<I: ?Sized, P: Parser<I = I>, T> Parser for MapParser<I, P, T>

type I = P::I

type O = T

fn parse<'a>(&self, data: &'a Self::I) -> ParseResult<&'a Self::I, Self::O>

impl<I: ?Sized, P: ParserCombinator<I = I>, T> Clone for MapParser<I, P, T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<I: ?Sized, P: ParserCombinator<I = I>, T> ParserCombinator for MapParser<I, P, T>

fn then<P: Parser<I = Self::I>>(&self, p: P) -> ChainedParser<Self, P>

Chain this parser with another parser, creating new parser that returns a tuple of their results

fn then_r<P: ParserCombinator<I = Self::I>>(
    &self,
    p: P
) -> MapParser<Self::I, ChainedParser<Self, P>, P::O>

Chain this parser with another parser, but toss the value from this parser

fn then_l<P: ParserCombinator<I = Self::I>>(
    &self,
    p: P
) -> MapParser<Self::I, ChainedParser<Self, P>, Self::O>

Chain this parser with another parser, but toss the value from the other parser

fn repeat(&self) -> RepeatParser<Self>

Create a new parser that will repeat this parser until it returns an error

fn map<T, F: 'static + Fn(Self::O) -> T>(
    &self,
    f: F
) -> MapParser<Self::I, Self, T>

Map the value of this parser

fn or<P: Parser<I = Self::I, O = Self::O>>(&self, p: P) -> OrParser<Self, P>

Create a disjunction with another parser. If this parser produces an error, the other parser will be used
