Struct BackoffNoticePayload 

pub struct BackoffNoticePayload {
    pub min_backoff_ns: u64,
    pub cause: BackoffCauseWire,
    pub suggested_next_send_ns: u64,
}

Wire-encoded BackoffNotice payload.

One of these rides as the sole SlotFill.payload of a BackoffNotice envelope. Field semantics:

• min_backoff_ns - minimum back-off duration the receiver is asking the sender to observe before its next envelope. The sender’s BackoffTable translates this into a next_retry_ns so the existing BackoffGateTx already gates outbound sends.
• cause - why the receiver is requesting back-off.
• suggested_next_send_ns - optional wall-clock hint (engine-ns since epoch) the receiver believes it will be ready by. None when the receiver has no estimate.

The payload uses bincode serialization (the universal SlotValue::to_wire_bytes impl at bb-ir/src/slot_value.rs:194-196 already routes through bincode), and the discriminator backoff_notice_type_hash is identical on both sides because it derives from std::any::type_name::<BackoffNoticePayload>() via FNV-1a.

Fields

min_backoff_ns: u64

Minimum back-off duration in nanoseconds.

cause: BackoffCauseWire

Why the receiver is requesting back-off.

suggested_next_send_ns: u64

Optional wall-clock hint (engine-ns since epoch) the receiver expects to be ready by. 0 encodes None.

Implementations

impl BackoffNoticePayload

pub fn new( min_backoff_ns: u64, cause: BackoffCause, suggested_next_send_ns: Option<u64>, ) -> Self

Construct a payload, encoding None as 0 per the field docstring.

pub fn suggested_next_send(&self) -> Option<u64>

Recover the optional wall-clock hint.

pub fn cause(&self) -> BackoffCause

Recover the framework-side BackoffCause.

pub fn encode(&self) -> Vec<u8>

Serialize via bincode. Matches the universal SlotValue::to_wire_bytes impl at bb-ir/src/slot_value.rs:194-196.

pub fn decode(bytes: &[u8]) -> Option<Self>

Deserialize via bincode. Returns None when the payload bytes don’t round-trip (corrupt envelope / version skew).

Trait Implementations

impl Clone for BackoffNoticePayload

fn clone(&self) -> BackoffNoticePayload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BackoffNoticePayload

impl Debug for BackoffNoticePayload

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BackoffNoticePayload

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for BackoffNoticePayload

impl PartialEq for BackoffNoticePayload

fn eq(&self, other: &BackoffNoticePayload) -> 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.

impl Serialize for BackoffNoticePayload

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
