Struct futures::stream::FuturesUnordered
source · [−]pub struct FuturesUnordered<Fut> { /* private fields */ }Expand description
A set of futures which may complete in any order.
See FuturesOrdered for a version of this
type that preserves a FIFO order.
This structure is optimized to manage a large number of futures.
Futures managed by FuturesUnordered will only be polled when they
generate wake-up notifications. This reduces the required amount of work
needed to poll large numbers of futures.
FuturesUnordered can be filled by collecting an
iterator of futures into a FuturesUnordered, or by
pushing futures onto an existing
FuturesUnordered. When new futures are added,
poll_next must be called in order to begin receiving
wake-ups for new futures.
Note that you can create a ready-made FuturesUnordered via the
collect method, or you can start with an empty set
with the FuturesUnordered::new constructor.
This type is only available when the std or alloc feature of this
library is activated, and it is activated by default.
Implementations
sourceimpl<Fut> FuturesUnordered<Fut>
impl<Fut> FuturesUnordered<Fut>
sourcepub fn new() -> FuturesUnordered<Fut>
pub fn new() -> FuturesUnordered<Fut>
Constructs a new, empty FuturesUnordered.
The returned FuturesUnordered does not contain any futures.
In this state, FuturesUnordered::poll_next will
return Poll::Ready(None).
sourcepub fn len(&self) -> usize
pub fn len(&self) -> usize
Returns the number of futures contained in the set.
This represents the total number of in-flight futures.
sourcepub fn push(&self, future: Fut)
pub fn push(&self, future: Fut)
Push a future into the set.
This method adds the given future to the set. This method will not
call poll on the submitted future. The caller must
ensure that FuturesUnordered::poll_next is called
in order to receive wake-up notifications for the given future.
