pub struct YieldStream<St, I> where
St: Stream<Item = I>, { /* fields omitted */ }
Expand description
A Stream
adapter that yields after every Poll::Ready(Some(_))
result
from its source.
The wrapper may be useful to ensure that a Future
that polls a Stream
(directly or indirectly) yields (return Poll::Pending
) between items. If
the source stream already returns Poll::Pending
then this will not add
further Poll::Pending
returns.
The type is enabled via the yield-stream feature.
Construct with source to wrap.
