Designing a domain error handling strategy requires categorizing errors by audience and recovery potential, then defining retry policies, fallbacks, and graceful degradation. This framework guides those decisions and clarifies who should manage the error and how recovery should occur.

Implementing graceful degradation and circuit breaker patterns in Rust involves using structured error management libraries like `thiserror` and `anyhow`. These patterns provide contextual debugging information and define recovery mechanisms for system errors.

Categorizing user-facing, internal, and system errors for retry strategies involves differentiating errors based on their audience and whether they are transient or permanent. This categorization determines whether to retry the operation, inform the user, or implement a fallback.

Yes, this error handling framework works directly with Rust `thiserror` and `anyhow` patterns. It utilizes these structured error management libraries to provide contextual information for debugging and to define clear recovery mechanisms.

Choosing between a fallback mechanism and a retry policy for payment processing failures depends on whether the error is transient or permanent. Use retry policies for temporary network issues, and implement fallbacks or inform the user when errors are permanent.
