What problem does it solve?

Provides a focused triage and troubleshooting guide for Resonate applications built with the Rust SDK, helping developers diagnose compile-time and runtime failures such as registration errors, serde serialization issues, tokio runtime mismatches, non-determinism during replay, and git-dependency install problems specific to the v0.1.0 SDK.

Core Features & Use Cases

• Structured triage flow: Step-by-step checks from compilation through registration, serde, runtime, and server compatibility to narrow down root causes quickly.
• Practical fixes and patterns: Concrete guidance on function signatures, serde derive requirements, tokio runtime annotations, spawn/await semantics, and how to avoid non-deterministic code paths in durable functions.
• Repro and verification: Tips for minimal repros, Cargo.toml git dependency pinning, using resonate CLI commands to inspect promise and invocation state, and cross-checking SDK vs server versions during bug reports.

Quick Start

Build and run a minimal Resonate Rust repro, check cargo build output for type errors, inspect registration results for signature or name mismatches, verify serde derives on inputs/outputs, and ensure your tokio runtime uses a multi-threaded flavor.
