fn parse_next(&mut self, i: I) -> IResult<I, O, E>

Take tokens from the Stream, turning it into the output

fn by_ref(&mut self) -> ByRef<'_, Self>where
    Self: Sized,

Treat &mut Self as a parser

fn value<O2>(self, val: O2) -> Value<Self, I, O, O2, E>where
    Self: Sized,
    O2: Clone,

Produce the provided value

fn void(self) -> Void<Self, I, O, E>where
    Self: Sized,

Discards the output of the Parser

fn output_into<O2>(self) -> OutputInto<Self, I, O, O2, E>where
    Self: Sized,
    O: Into<O2>,

Convert the parser’s output to another type using std::convert::From

fn recognize(self) -> Recognize<Self, I, O, E>where
    Self: Sized,
    I: Stream + Offset,

Produce the consumed input as produced value.

fn with_recognized(self) -> WithRecognized<Self, I, O, E>where
    Self: Sized,
    I: Stream + Offset,

Produce the consumed input with the output

fn map<G, O2>(self, map: G) -> Map<Self, G, I, O, O2, E>where
    G: Fn(O) -> O2,
    Self: Sized,

Maps a function over the output of a parser

fn map_res<G, O2, E2>(self, map: G) -> MapRes<Self, G, I, O, O2, E, E2>where
    Self: Sized,
    G: FnMut(O) -> Result<O2, E2>,
    I: Clone,
    E: FromExternalError<I, E2>,

Applies a function returning a Result over the output of a parser.

    Self: Sized,
    G: FnMut(O) -> H,

    Self: Sized,
    I: Stream,
    E: ContextError<I, C>,
    C: Clone + Debug,

If parsing fails, add context to the error

fn complete_err(self) -> CompleteErr<Self>where
    Self: Sized,

Transforms Incomplete into Backtrack

fn err_into<E2>(self) -> ErrInto<Self, I, O, E, E2>where
    Self: Sized,
    E: Into<E2>,
