fn by_ref(&mut self) -> &mut Self where
    Self: Sized, 

Borrows a parser instead of consuming it.

fn with<P2>(self, p: P2) -> With<Self, P2> where
    Self: Sized,
    P2: Parser<Input>, 

Discards the value of the self parser and returns the value of p. Fails if any of the parsers fails.

fn skip<P2>(self, p: P2) -> Skip<Self, P2> where
    Self: Sized,
    P2: Parser<Input>, 

Discards the value of the p parser and returns the value of self. Fails if any of the parsers fails.

fn and<P2>(self, p: P2) -> (Self, P2) where
    Self: Sized,
    P2: Parser<Input>, 

Parses with self followed by p. Succeeds if both parsers succeed, otherwise fails. Returns a tuple with both values on success.

fn or<P2>(self, p: P2) -> Or<Self, P2> where
    Self: Sized,
    P2: Parser<Input, Output = Self::Output>, 

Returns a parser which attempts to parse using self. If self fails without consuming any input it tries to consume the same input using p.

fn then<N, F>(self, f: F) -> Then<Self, F> where
    Self: Sized,
    F: FnMut(Self::Output) -> N,
    N: Parser<Input>, 

Parses using self and then passes the value to f which returns a parser used to parse the rest of the input.

fn then_partial<N, F>(self, f: F) -> ThenPartial<Self, F> where
    Self: Sized,
    F: FnMut(&mut Self::Output) -> N,
    N: Parser<Input>, 

Variant of then which parses using self and then passes the value to f as a &mut reference.

fn map<F, B>(self, f: F) -> Map<Self, F> where
    Self: Sized,
    F: FnMut(Self::Output) -> B, 

Uses f to map over the parsed value.

    Self: Sized,
    F: FnMut(Self::Output, &mut Input) -> B, 

fn flat_map<F, B>(self, f: F) -> FlatMap<Self, F> where
    Self: Sized,
    F: FnMut(Self::Output) -> Result<B, <Input as StreamOnce>::Error>, 

Uses f to map over the output of self. If f returns an error the parser fails.

fn message<S>(self, msg: S) -> Message<Self, S> where
    Self: Sized,
    S: for<'s> ErrorInfo<'s, Input::Token, Input::Range>, 

Parses with self and if it fails, adds the message msg to the error.

fn expected<S>(self, msg: S) -> Expected<Self, S> where
    Self: Sized,
    S: for<'s> ErrorInfo<'s, Input::Token, Input::Range>, 

Parses with self and if it fails without consuming any input any expected errors are replaced by msg. msg is then used in error messages as "Expected msg".

fn silent(self) -> Silent<Self> where
    Self: Sized, 

Parses with self, if it fails without consuming any input any expected errors that would otherwise be emitted by self are suppressed.

fn and_then<F, O, E>(self, f: F) -> AndThen<Self, F> where
    Self: Parser<Input> + Sized,
    F: FnMut(Self::Output) -> Result<O, E>,
    E: Into<<Input::Error as ParseError<Input::Token, Input::Range, Input::Position>>::StreamError>, 

Parses with self and applies f on the result if self parses successfully. f may optionally fail with an error which is automatically converted to a ParseError.
