Trait combine::primitives::RangeStream

pub trait RangeStream: Stream {
    fn uncons_range(
        &mut self, 
        size: usize
    ) -> Result<Self::Range, Error<Self::Item, Self::Range>>;
    fn uncons_while<F>(
        &mut self, 
        f: F
    ) -> Result<Self::Range, Error<Self::Item, Self::Range>>
    where
        F: FnMut(Self::Item) -> bool;
}

A RangeStream is an extension of Stream which allows for zero copy parsing.

Required Methods

fn uncons_range(
    &mut self,
    size: usize
) -> Result<Self::Range, Error<Self::Item, Self::Range>>

Takes size elements from the stream. Fails if the length of the stream is less than size.

fn uncons_while<F>(
    &mut self,
    f: F
) -> Result<Self::Range, Error<Self::Item, Self::Range>> where
    F: FnMut(Self::Item) -> bool, 

Takes items from stream, testing each one with predicate. returns the range of items which passed predicate.
