pub struct MapExp<P: Parser, F: Fn(Expected) -> Expected> { /* fields omitted */ }

Trait Implementations

impl<P: Parser, F: Fn(Expected) -> Expected> Parser for MapExp<P, F>

type Out = P::Out

fn parse<'a>(&self, it: &LCChars<'a>) -> ParseRes<'a, P::Out>

fn expected(&self) -> Expected

fn parse_s(&self, s: &str) -> Result<Self::Out, ParseError>

fn parse_sn<'a>(&self, s: &'a str) -> Result<(&'a str, Self::Out), ParseError>

fn then<P: Parser<Out = V2>, V2>(self, b: P) -> Then<Self, P>

returns a parser that will combine the results of this and the given parser into a tuple

fn then_ig<P: Parser<Out = V2>, V2>(self, b: P) -> ThenIg<Self, P>

returns a Parser that will require the given parser completes, but ignores its result useful for dropping brackets and whitespace

fn ig_then<P: Parser<Out = V2>, V2>(self, b: P) -> IgThen<Self, P>

returns a Parser that will require this parser completes, but only return the result of the given parser useful for dropping brackets and whitespace etc

fn or<P: Parser<Out = Self::Out>>(self, p: P) -> Or<Self, P>

Returns a Parser that will try both child parsers, (A first) and return the first successfl result

fn map<F: Fn(Self::Out) -> V2, V2>(self, f: F) -> Map<Self, V2, F>

Returns a Parser that converts the result of a successful parse to a different type. Much like map on iterators and Result

fn try_map<F: Fn(Self::Out) -> Result<V2, Expected>, V2>(
    self,
    f: F
) -> TryMap<Self, V2, F>

Returns a Parser that converts the result of a successful parse to a different type. however the map function can fail and return a result The Error type should be err::ECode, this does not have line associated. That will be attacked by the TryMap object so this will pass that error up correctly

fn asv<R: Clone>(self, r: R) -> As<Self, R>

fn ig(self) -> As<Self, ()>

fn map_exp<F: Fn(Expected) -> Expected>(self, f: F) -> MapExp<Self, F>

fn brk(self) -> Break<Self>
