Struct futures::stream::SelectAll [−][src]
An unbounded set of streams
This “combinator” provides the ability to maintain a set of streams and drive them all to completion.
Streams are pushed into this set and their realized values are yielded as they become ready. Streams will only be polled when they generate notifications. This allows to coordinate a large number of streams.
Note that you can create a ready-made SelectAll via the
select_all function in the stream module, or you can start with an
empty set with the SelectAll::new constructor.
Implementations
impl<St> SelectAll<St> where
St: Stream + Unpin, [src]
St: Stream + Unpin,
pub fn new() -> SelectAll<St>[src]
Constructs a new, empty SelectAll
The returned SelectAll does not contain any streams and, in this
state, SelectAll::poll will return Poll::Ready(None).
pub fn len(&self) -> usize[src]
Returns the number of streams contained in the set.
This represents the total number of in-flight streams.
pub fn is_empty(&self) -> bool[src]
Returns true if the set contains no streams
pub fn push(&mut self, stream: St)[src]
Push a stream into the set.
This function submits the given stream to the set for managing. This
function will not call poll on the submitted stream. The caller must
ensure that SelectAll::poll is called in order to receive task
notifications.
