Enum Reliability 

pub enum Reliability {
    FireAndForget,
    Reliable,
}

Reliability mode chosen per stream.

Variants

FireAndForget

Send packets and forget. No retransmission, no ordering recovery, no ACK/NACK tracking. Monotonic sequence numbers on the wire so callers that care can detect gaps / reorder themselves.

Reliable

Retransmit lost packets (receiver NACKs + a sender timeout backstop; the retransmit window is sized to the tx-window so nothing in flight is unrecoverable). Guarantees gap-free eventual delivery of every byte.

Ordering contract (H-8): the substrate does NOT reorder for you. Accepted packets — including out-of-order arrivals and retransmits — are delivered to the inbound queue in arrival order, each tagged with its monotonic seq. A consumer that needs strict in-order bytes must reassemble by seq itself (the blob-transfer engine’s per-stream reorder buffer is the reference example). Consumers that frame their own ordering (nRPC streaming keys on EventMeta/call_id) or tolerate reordering need do nothing. Reliable here means “no loss”, not “delivered in order”.

Trait Implementations

impl Clone for Reliability

fn clone(&self) -> Reliability

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Reliability

impl Debug for Reliability

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for Reliability

impl PartialEq for Reliability

fn eq(&self, other: &Reliability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
