Failsafe-go is a library for building fault tolerant Go applications. It works by wrapping executable logic with one or more resilience policies, which can be combined and composed as needed. Policies include:
• Failure handling: Retry, Fallback
• Load limiting: Circuit Breaker, Bulkhead, Rate Limiter, Cache
• Time limiting: Timeout, Hedge
