Enum AllocFailReason 

pub enum AllocFailReason {
    HeapExhausted,
    PerItemCapExceeded {
        cap: usize,
    },
}

Why a fallible-allocation boundary refused to admit bytes into engine state. Carried by WireReceiveErrorKind::AllocationFailed and AppIngressErrorKind::AllocationFailed.

Variants

HeapExhausted

Vec::try_reserve_exact (or equivalent fallible-allocator call) returned TryReserveError. The host’s allocator has no headroom for the request.

PerItemCapExceeded

A caller-side per-item cap (e.g. EnvelopeCaps::max_per_fill_bytes, NodeConfig::max_app_event_bytes, NodeConfig::max_invoke_bytes) rejected the request before any allocation was attempted.

Fields

cap: usize

The cap value the boundary enforced.

Trait Implementations

impl Clone for AllocFailReason

fn clone(&self) -> AllocFailReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocFailReason

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

Formats the value using the given formatter.

impl Eq for AllocFailReason

impl PartialEq for AllocFailReason

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