Crate cymule_core 

The small, deterministic Cymule semantic kernel.

This crate owns canonical identity, the frozen IR, command admission, state-machine reduction, and replay. It deliberately performs no ambient I/O.

Structs

ArtifactRecord

Immutable artifact bytes held by the embedded store.

ArtifactRef

Immutable artifact reference.

AttemptProjection

Fenced attempt projection.

CommandEnvelope

A preconditioned, idempotent command proposal.

CommandReceipt

Durable command receipt.

CompactionCertificate

Compaction witness. The Embedded profile constructs and validates this type but does not delete canonical history automatically.

ComponentContract

Abstract executable component contract.

Definition

A named Flow definition.

EffectContract

Abstract world-effect contract.

EffectProfile

Orthogonal effect properties used by admission and binding.

EffectProjection

Effect projection with immutable occurrence binding.

Event

A canonical event.

Machine

In-memory reference machine for the Semantic Interpreter and Embedded profiles. All ambient I/O belongs in higher-level runtime crates.

MachineBaseSnapshot

One verified canonical base projection replacing a causally closed prefix.

MachineCompaction

Portable evidence returned after compacting one canonical event prefix.

MachineSnapshot

Portable, provider-neutral snapshot of canonical inputs and optional base.

ObligationProjection

Scope-transferred world-effect obligation.

PlanCandidate

An unsealed, language-neutral semantic plan.

Projection

Rebuildable full projection.

Region

A structured sequence with an explicit result expression.

RunProjection

Rebuildable Run projection.

ScopeProjection

Scope projection.

SealedPlan

An immutable sealed plan.

Step

A stable operation site.

Enums

Command

Commands admitted by the semantic kernel.

CommandReceiptStatus

Public command outcome.

CoreError

Stable semantic error categories.

DispatchPolicy

Effect release policy.

EffectPhase

Effect control phase.

EffectTransition

Legal effect transitions.

EventPayload

Canonical transition payloads.

Expression

Pure expressions over input, prior bindings, and literals.

MutationKind

Effect mutation class.

Operation

Frozen structured operations. Complex frontend syntax lowers to these five semantic boundaries.

ReconciliationMode

Reconciliation capability.

ReconciliationResolution

Reconciliation result transition.

ReconciliationState

Reconciliation state.

ReplayAvailability

Explicit exact-replay capability.

RunStatus

Public Run status.

ScopeMode

Scope behavior profile.

ScopeStatus

Scope lifecycle state.

WaitSpec

Durable wait descriptions.

WorldOutcome

Observed external-world outcome.

Constants

COMMAND_VERSION

Public command version.

EVENT_VERSION

Canonical event version.

IR_VERSION

Frozen canonical IR version.

ROOT_SCOPE_ID

Stable root scope identifier within every Run.

SEMANTIC_VERSION

Semantic specification version.

Functions

canonical_bytes

Serialize a value using RFC 8785 JSON Canonicalization Scheme.

canonical_digest

Compute a canonical digest without an identity prefix.

content_id

Compute a domain-separated content identifier for canonical JSON.

effect_intent_id

Derive the structural identity of one intentional effect occurrence.

effect_obligation_id

Derive a stable obligation identity from an intent.

sha256_bytes

Compute a lowercase hexadecimal SHA-256 digest.

Type Aliases

Result

Result type used by the semantic kernel.
