Build durable applications in Rust: the Temporal Rust SDK is now generally available
Summary
The Temporal Rust SDK is now generally available, enabling Rust developers to build durable, fault-tolerant applications with native APIs for Workflows and Activities. It manages execution state, retries, and recovery for long-running processes.
- The Rust SDK provides native APIs for Workflows and Activities using async functions, structs, and procedural macros.
- Workflows must be deterministic, using SDK primitives for timers and concurrency instead of direct Tokio or std library calls.
- Activities handle external I/O and side effects; they should be idempotent as they may run multiple times.
- A runtime nondeterminism detector is included to help identify violations in Workflow code.
Rust engineers building complex, long-running, and fault-tolerant distributed applications can now leverage Temporal's state management and reliability with a native SDK.
