Struct wlancfg_lib::util::future_with_metadata::FutureWithMetadata
source · pub struct FutureWithMetadata<F, M> {
pub metadata: M,
/* private fields */
}
Expand description
Wraps a future in order to allow reading/writing of “metadata” while the future is pending. When the future finishes, it will resolve with a tuple: (inner_fut::Output, metadata).

§fn on_timeout<WT, OT>(self, time: WT, on_timeout: OT) -> OnTimeout<Self, OT>
fn on_timeout<WT, OT>(self, time: WT, on_timeout: OT) -> OnTimeout<Self, OT>
Wraps the future in a timeout, calling
on_timeout
to produce a result
when the timeout occurs.§fn on_stalled<OS>(
self,
timeout: Duration,
on_stalled: OS
) -> OnStalled<Self, OS>
fn on_stalled<OS>( self, timeout: Duration, on_stalled: OS ) -> OnStalled<Self, OS>
Wraps the future in a stall-guard, calling
on_stalled
to produce a result
when the future hasn’t been otherwise polled within the timeout
.
This is a heuristic - spurious wakeups will keep the detection from triggering,
and moving all work to external tasks or threads with force the triggering early.
