What problem does it solve?

Rust developers building long-running, crash-safe workflows need a structured pattern to declare durable functions, manage context and results, and ensure checkpoint-replay semantics with a clean API surface.

Core Features & Use Cases

• Durable function patterns: Workflow, Leaf with Info, and Pure leaf shapes using #[resonate::function].
• Context APIs: Use ctx.run, ctx.rpc, and ctx.sleep (with Duration) and .spawn() for parallelism, plus builder options for timeouts and routing.
• Use Case: Orchestrate a multi-step Rust workflow that loads data, processes it in parallel, and handles retries with checkpointing.

Quick Start

Define a simple Rust function annotated with #[resonate::function] to implement a small workflow that calls a leaf with ctx.run and returns a Result.
