PhoenixGenApi.WorkerPool.CircuitBreaker (PhoenixGenApi v2.13.0)

Shared circuit breaker functions for WorkerPool and Worker.

This module provides common circuit breaker logic to avoid code duplication between the pool-level and worker-level circuit breakers.

Summary

Checks if the circuit breaker is open (in cooldown period).

Checks if the circuit breaker is open (in cooldown period).

Returns true if the circuit breaker is open (rejecting requests), false if requests should be allowed.

circuit_open_at: The monotonic time (in milliseconds) when the circuit was opened, or nil if the circuit is closed.
cooldown_ms: The cooldown period in milliseconds.

iex> CircuitBreaker.circuit_open?(nil, 5000)
false

iex> now = System.monotonic_time(:millisecond)
iex> CircuitBreaker.circuit_open?(now, 5000)
true
