pub struct FnParser<I, F>(_, _);

Trait Implementations

impl<I: Clone, F: Clone> Clone for FnParser<I, F>

fn clone(&self) -> FnParser<I, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I, O, F> Parser for FnParser<I, F> where I: Stream, F: FnMut(State<I>) -> ParseResult<O, I, I::Item>

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
