Expand description
A stream of values, not all of which may have been produced yet.
This is similar to futures_util::stream::Stream
trait, except it works with Actor
Associated Types
Required methods
Provided methods
Converts a stream of type T
to a stream of type U
.
Chain on a computation for when a value is ready, passing the resulting
item to the provided closure f
.
Execute an accumulating computation over a stream, collecting all the values into one final result.
Add timeout to stream.
err
value get returned as a timeout error.
fn finish(self) -> StreamFinish<Self> where
Self: Sized + Unpin,
fn finish(self) -> StreamFinish<Self> where
Self: Sized + Unpin,
Converts a stream to a future that resolves when stream finishes.
