Struct async_nursery::NurseryStream [−][src]
pub struct NurseryStream<Out> { /* fields omitted */ }
Expand description
Collection of JoinHandle
s of tasks spawned on the nursery. When this is dropped,
all spawned tasks are canceled. You can poll the [Stream
] implementation on this
to obtain the outputs of your tasks. You can await the Future
implementation if
you don’t care about the outputs but just want to wait until all spawned tasks are done.
Implementations
Close this NurseryStream. Related Nursery
will no longer be able to
spawn. This allows the stream to end. Alternatively you can drop all related
Nursery
or call Nursery::close_nursery
.
Trait Implementations
Returns true
if the underlying future should no longer be polled.
Returns true
if the stream should no longer be polled.
A hint of the number of tasks currently being awaited. There is no upper bound,
because we don’t keep track of the tasks that are in the channel between the Nursery
and
the NurseryStream
.
type Item = Out
type Item = Out
Values yielded by the stream.
