Delivery

byteflow::scheduler

Enum Delivery

pub enum Delivery {
    Queued,
    QueuedDropOldest,
    DroppedNewest,
    Handoff(Box<Flow>),
}

Expand description

Outcome of pushing a message.

Queued* means the hop (or a replacement under DropOldest) lives in the inbox for a later Receive. Handoff means a parked flow was waiting for this hop — the caller (worker::deliver / crate::Runtime::send) must resume_with and re-enqueue the flow. Dropped variants never wake a waiter.
