Trait combine::StreamOnce
[−]
[src]
pub trait StreamOnce { type Item: Clone + PartialEq; type Range: Clone + PartialEq; fn uncons(&mut self) -> Result<Self::Item, Error<Self::Item, Self::Range>>; }
StreamOnce
represents a sequence of items that can be extracted one by one.
Associated Types
type Item: Clone + PartialEq
The type of items which is yielded from this stream.
type Range: Clone + PartialEq
The type of a range of items yielded from this stream.
Types which do not a have a way of yielding ranges of items should just use the
Self::Item
for this type.
Required Methods
fn uncons(&mut self) -> Result<Self::Item, Error<Self::Item, Self::Range>>
Takes a stream and removes its first item, yielding the item and the rest of the elements.
Returns Err
if no element could be retrieved.
