Enum ObserverTrapClass 

#[non_exhaustive]
#[repr(u8)]
pub enum ObserverTrapClass {
    Panic = 0,
    BudgetExceeded = 1,
    CapabilityDenied = 2,
    Other = 3,
}

Trap classification for ObserverQuarantine — surfaced into the chain-anchored receipt so replay + audit can distinguish each sandbox-boundary failure mode.

Wire-stable enum (mirrors RuntimeSignatureClass / ComplianceTier): #[repr(u8)] + #[non_exhaustive] so additive expansion is non-breaking. Each variant has a fixed discriminant so the postcard wire format stays stable across schema-version bumps.

Mirrored as a host-internal type by arkhe_forge_platform::observer_host (re-exports this same enum). Single source of truth lives here in arkhe-forge-core because the value enters the L0 chain via the ObserverQuarantine event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Panic = 0

wasm panic / cranelift trap — observer code itself faulted.

BudgetExceeded = 1

Fuel exhaustion — observer exceeded the per-invocation budget.

CapabilityDenied = 2

Observer attempted to call a host-fn for which the active per-invocation capability set lacks the matching token.

Other = 3

Catch-all for cranelift trap variants not classified above (incl. operator host-config errors like “no capability impl registered” — distinguished only at audit-log granularity).

Trait Implementations

impl Clone for ObserverTrapClass

fn clone(&self) -> ObserverTrapClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObserverTrapClass

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObserverTrapClass

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ObserverTrapClass

fn eq(&self, other: &ObserverTrapClass) -> 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 ObserverTrapClass

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
