pub struct Then<P, F>(_, _);

Trait Implementations

impl<P: Clone, F: Clone> Clone for Then<P, F>

fn clone(&self) -> Then<P, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P, N, F> Parser for Then<P, F> where F: FnMut(P::Output) -> N, P: Parser, N: Parser<Input=P::Input>

type Input = N::Input

A type implementing the Stream trait which is the specific type that is parsed.

type Output = N::Output

The type which is returned when the parsing is successful.

fn parse_state(&mut self, input: State<Self::Input>) -> ParseResult<Self::Output, Self::Input>

Parses using the state input by calling Stream::uncons one or more times On success returns Ok((value, new_state)) on failure it returns Err(error)

fn parse(&mut self, input: Self::Input) -> Result<(Self::Output, Self::Input), ParseError>

Entrypoint of the parser Takes some input and tries to parse it returning a ParseResult
