Enum BackoffCause 

pub enum BackoffCause {
    QueueFull,
    PhiAccrual,
    ExplicitDrop,
}

Why the receiver is requesting a back-off.

Mirrors the wire-protocol BackoffCause payload field; lives on the framework side so the engine + bus events reference the same enum the wire op encodes.

Variants

QueueFull

IngressQueue depth crossed the high-water mark.

PhiAccrual

PhiAccrualState marked the sender as Suspect (sender is too fast for this receiver’s processing rate).

ExplicitDrop

A Component returned a typed reject (e.g. role rate-limit such as an aggregator already filled its per-round window).

Trait Implementations

impl Clone for BackoffCause

fn clone(&self) -> BackoffCause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BackoffCause

impl Debug for BackoffCause

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

Formats the value using the given formatter.

impl Eq for BackoffCause

impl From<BackoffCause> for BackoffCauseWire

fn from(cause: BackoffCause) -> Self

Converts to this type from the input type.

impl From<BackoffCauseWire> for BackoffCause

fn from(cause: BackoffCauseWire) -> Self

Converts to this type from the input type.

impl PartialEq for BackoffCause

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