Enum AppIngressErrorKind 

pub enum AppIngressErrorKind {
    AllocationFailed {
        reason: AllocFailReason,
    },
    BudgetExceeded {
        budget_remaining: usize,
    },
    PerItemCapExceeded {
        cap: usize,
    },
}

Sub-kind discriminator for InfraEvent::AppIngressError. One top-level variant + sub-kind keeps the bus-topic count down - subscribers route on the variant name and match the sub-kind out of the event’s fields when they need to distinguish allocation failure from budget exhaustion from a per-item cap.

Variants

AllocationFailed

Fallible reservation of the engine-side ingress buffer returned TryReserveError or hit a per-item cap before allocation was attempted.

Fields

reason: AllocFailReason

Why the reservation failed.

BudgetExceeded

Admitting this payload would push the engine over NodeConfig::ingress_byte_budget.

Fields

budget_remaining: usize

Bytes still available under NodeConfig::ingress_byte_budget at the time of the rejection.

PerItemCapExceeded

A per-item cap (max_app_event_bytes, max_invoke_inputs, max_invoke_bytes, or max_completion_result_bytes) rejected the payload before any allocation was attempted. The host’s synchronous deliver_event / invoke call returns DeliveryError::OversizePayload in addition to this bus emission.

Fields

cap: usize

The cap value the boundary enforced.

Trait Implementations

impl Clone for AppIngressErrorKind

fn clone(&self) -> AppIngressErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppIngressErrorKind

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

Formats the value using the given formatter.

impl Eq for AppIngressErrorKind

impl PartialEq for AppIngressErrorKind

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