This is a fault tolerance library for Go designed to prevent cascading failures by isolating unhealthy remote services using the circuit breaker pattern. It serves as a resilience tool for managing request timeouts, defining fallback logic, and protecting remote systems from overloading. The library differentiates itself through the integration of a health metrics exporter that streams real-time performance and status data of remote connections to external monitoring tools. It combines this observability with a circuit breaker state machine that tracks success and failure rates to block calls
