Trait Implementations

impl<P1: Clone, P2: Clone> Clone for Or<P1, P2> where P1: Parser, P2: Parser

fn clone(&self) -> Or<P1, P2>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I, O, P1, P2> Parser for Or<P1, P2> where I: Stream, P1: Parser<Input=I, Output=O>, P2: Parser<Input=I, Output=O>

type Input = I

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

type Output = O

The type which is returned when the parsing is successful.

fn parse_state(&mut self, input: State<I>) -> ParseResult<O, I, I::Item>

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<Self::Input::Item>>

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