PushResult

Enum PushResult 

Source
pub enum PushResult {
    Accepted,
    DroppedNewest(StreamItem),
    DroppedOldest(StreamItem),
    Rejected(StreamItem),
    Closed(StreamItem),
}
Expand description

Outcome of pushing a single packet into a push stream.

The variant records what the spine did with the packet under the active BufferPolicy. Every variant except PushResult::Accepted carries the packet back so the caller can route the rejected or evicted item elsewhere. Map a result to its kernel-facing BackpressureOutcome with PushResult::outcome.

Variants§

§

Accepted

The packet was admitted to the queue.

§

DroppedNewest(StreamItem)

The queue was full; this newest packet was dropped under the drop-newest policy.

§

DroppedOldest(StreamItem)

The queue was full; the oldest queued packet was evicted to make room, and that evicted packet is returned here.

§

Rejected(StreamItem)

The queue was full and the error policy refused the push; the packet is returned unaccepted.

§

Closed(StreamItem)

The stream was already closed; the packet is returned unaccepted.
