Enumeration Type Documentation

circuit_state

enum class kcenon::common::resilience::circuit_state

strong

Represents the current state of a circuit breaker.

State Transitions: CLOSED -> OPEN: When failure threshold is exceeded OPEN -> HALF_OPEN: After timeout period expires HALF_OPEN -> CLOSED: When success threshold is met HALF_OPEN -> OPEN: When any failure occurs during testing

Enumerator
CLOSED	Normal operation state. Requests are allowed and failures are tracked.
OPEN	Failure state. Requests are immediately rejected without execution. Transitions to HALF_OPEN after timeout.
HALF_OPEN	Recovery testing state. Limited requests are allowed to test if service has recovered.
