Enum RouteError

        expected: String,
        found: String,

    InvalidEventEnvelope {

Reasons the router refused a crate::CallbackRequest before dispatch.

Variants are intentionally fine-grained: each acceptance-criterion failure class gets its own variant so a future super::FailureMapper can map them onto distinct crate::FailureClass values without inspecting strings.

Variants

SchemaVersionMismatch

schema_version on the inbound request did not match the router’s compiled-in crate::SCHEMA_VERSION.

Fields

expected: String

found: String

EmptySentinel

A required identifier was the empty sentinel string. Carries the field path for diagnostics.

Fields

field: &'static str

UnknownEventName

The deserialized request carried an event-kind value that is not part of the wire vocabulary.

In practice serde rejects unknown enum wire names at deserialize time, but the variant exists so non-serde call sites (e.g. a future text-protocol bridge) can surface the same failure class without inventing a parallel error type.

Fields

received: String

UnknownEnumName

The deserialized request carried an enum value other than the event kind (e.g. integration_mode) whose wire name is not in the vocabulary. Preserved as a separate variant from Self::UnknownEventName so the failure class is unambiguous when mapping to a receipt.

Fields

field: &'static str

received: String

InvalidFrameContext

frame_context violated a structural invariant: required for the event but absent, or partially populated (e.g. parent_frame_id without frame_id, or any frame field set without frame_class).

Fields

detail: String

InvalidPayloadRef

A payload reference failed structural validation (empty payload_id / payload_kind). Body semantics are opaque to the router — this only catches sentinel-empty fields on the reference itself.

Fields

index: usize

detail: String

InvalidEventEnvelope

The request’s event is structurally illegal for this envelope (e.g. receipt.emitted carrying an idempotency_key). Distinct from frame-context errors so the failure class is unambiguous.

Fields

detail: String

AdapterIdNotFound

No registered adapter has an adapter_id matching the request. Distinct from Self::AdapterVersionMismatch.

Fields

adapter_id: String

AdapterVersionMismatch

An adapter with the requested adapter_id is registered, but its adapter_version does not match the request. Carries both versions so a client can surface a precise upgrade suggestion.

Fields

adapter_id: String

requested: String

registered: String
