error-handling-patterns

Implement cross-language error handling by applying language-specific patterns like Python custom exceptions, TypeScript error classes, Rust Result types, and Go error conventions to build fault-tolerant distributed systems.

Handle Rust Result and Option types by adopting result-based error handling patterns. This approach replaces exception throwing with explicit type returns, ensuring robust error management by forcing the caller to handle potential failure cases directly.

A circuit breaker works for API services and background workers by tripping after a failure threshold is reached, blocking downstream calls to prevent cascading failures and enabling graceful degradation in distributed systems.

Yes, you can use these templates for Python and Go microservices. The guidelines provide Python custom exceptions and Go error conventions alongside universal error aggregation patterns to increase system reliability.

Use exception-based patterns in TypeScript for unexpected failures via custom error classes, while result-based patterns handle expected, recoverable failures, allowing API services to manage errors gracefully without breaking execution flow.

You need error aggregation and graceful degradation patterns because they allow distributed systems to collect multiple errors and maintain partial functionality, preventing total system failure during partial outages and increasing overall system reliability.
