Error Handling and Fault Tolerance

What problem does it solve?

Standardizes how Rust crates define and handle errors, enabling consistent retry logic and graceful degradation across components such as ASR, LLM, and TTS pipelines.

Core Features & Use Cases

• Error type conventions: guidelines for defining error enums and implementing ComponentError.
• Retry and fallback patterns: demonstrated strategies, including a FallbackAsrProvider and a structured retry matrix.
• Graceful degradation: describes how to respond to failures when recovery is not possible, including client-facing error codes and session termination.

Quick Start

Implement a simple ComponentError for your error type and wire a fallback provider to illustrate graceful degradation.
