What problem does it solve?

Coordinates multi-step distributed workflows in Rust that must remain consistent across partial failures by pairing forward actions with compensating rollbacks so overall system state can be unwound safely.

Core Features & Use Cases

• Forward and compensating actions: Show how to run ordered durable forward steps and dispatch reverse compensations in Rust using Result and match-based enum dispatch.
• Durable checkpoints and resume semantics: Explain how each forward step becomes a durable checkpoint so the saga can resume after worker crashes.
• Operational safeguards: Emphasizes idempotent compensations, timeouts, and retry strategies for realistic order processing scenarios (inventory, payment, shipment).
• Use Case: Implement an order placement saga that reserves inventory, charges payment, and creates shipment, and that reverses completed steps if a later step fails.

Quick Start

Run a Rust saga that reserves inventory, charges payment, and creates shipment for order 12345 and revert completed steps automatically on failure.
