Struct rcombinators::combinators::Ignore

pub struct Ignore<Inner: Parser> { /* fields omitted */ }

Ignore ignores the result of an inner parser, effectively hiding the result. Useful if consumed input should not be processed further, and simplifies types in combined parsers.

Methods

impl<Inner: Parser> Ignore<Inner>

pub fn new(p: Inner) -> Ignore<Inner>

Trait Implementations

impl<R, P: Parser<Result = R>> Parser for Ignore<P>

type Result = ()

fn parse(
    &mut self,
    st: &mut ParseState<impl Iterator<Item = char>>
) -> ParseResult<Self::Result>

parse consumes input from st and returns a result or an error.

fn apply<R2, F: Fn(Self::Result) -> ParseResult<R2>>(
    self,
    f: F
) -> Transform<Self::Result, R2, Self, F> where
    Self: Sized, 

apply transforms the result of this parser using a Transform combinator.

fn then<R2, P: Parser<Result = R2>>(self, p: P) -> Then<Self, P> where
    Self: Sized, 

then attempts to parse input, and if it succeeds, executes parser p, only returning p's result. This is useful for chaining parsers of which the results are not need.
