Trait chomp::buffer::Stream

pub trait Stream<'a, 'i> {
    type Input: Input + 'i;
    fn parse<F, T, E>(
        &'a mut self, 
        f: F
    ) -> Result<T, StreamError<<Self::Input as Input>::Buffer, E>>
    where
        F: FnOnce(Self::Input) -> ParseResult<Self::Input, T, E>,
        T: 'i,
        E: 'i;
}

Trait wrapping the state management in reading from a data source while parsing.

Associated Types

type Input: Input + 'i

The input item type, usually depending on which DataSource is used.

Required Methods

fn parse<F, T, E>(
    &'a mut self,
    f: F
) -> Result<T, StreamError<<Self::Input as Input>::Buffer, E>> where
    F: FnOnce(Self::Input) -> ParseResult<Self::Input, T, E>,
    T: 'i,
    E: 'i, 

Attempts to run the supplied parser F once on the currently populated data in this stream, providing a borrow of the inner data storage.

If a StreamError::Retry is returned the consuming code it should just retry the action (the implementation might require a separate call to refill the stream).

Implementors

• impl<'a, S: DataSource, B: Buffer<S::Item>> Stream<'a, 'a> for Source<S, B> where
    S::Item: 'a, 
• impl<'a, 'i, I: 'i + Copy + PartialEq> Stream<'a, 'i> for SliceStream<'i, I>
