SYSTEM DOCUMENTATION & REQUIREMENTS

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.

Frequently Asked Questions about Error Handling and Fault Tolerance

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I standardize error handling and retry logic across multiple Rust crates?▼

Graceful degradation in Rust pipelines is achieved by defining recoverable versus unrecoverable errors and applying fallback strategies, such as a FallbackAsrProvider, to maintain service availability when a component fails.

What is the best way to handle WebSocket session termination when encountering unrecoverable errors in Rust?▼

Handle WebSocket session termination by categorizing the failure as an unrecoverable error via ComponentError, then applying documented graceful degradation patterns that return client-facing error codes and safely close the session.

Can I use this error handling approach for ASR, LLM, and TTS pipeline components in Rust?▼

Yes, this error handling approach explicitly applies to multi-crate Rust components including ASR, LLM, and TTS pipelines, providing standardized error type conventions and a structured retry matrix for these specific workflows.

How do I implement a fallback provider for a Rust ASR pipeline when recovery is not possible?▼

Implement a fallback provider by wiring a FallbackAsrProvider into your ASR pipeline, which demonstrates how to respond to failures when recovery is not possible by switching to an alternative component.
