Crate durable_workflow 

Minimal Rust SDK for the Durable Workflow worker protocol.

The crate covers the v1 Rust round-trip: start, signal, query, and durably sleep in workflows; register a Rust worker; poll workflow, activity, and read-only query tasks; reconstruct typed workflow-instance state through deterministic replay; heartbeat worker and activity liveness; and exchange JSON-native payloads through the same avro generic wrapper used by the existing first-party SDKs.
