Configuration for the CircuitBreaker.

Defines thresholds and timeouts that control the behavior of the circuit breaker.

Fields

failure_threshold: usize

The number of consecutive failures after which the circuit opens.

failure_rate_threshold: f64

The failure rate (0.0 to 1.0) within the sliding window that causes the circuit to open.

minimum_request_threshold_for_rate: usize

The minimum number of requests in the sliding window before the failure rate is considered.

success_threshold_to_close: usize

The number of consecutive successes required in HalfOpen state to transition to Closed.

reset_timeout: Duration

The duration the circuit stays Open before transitioning to HalfOpen.

half_open_max_concurrent_operations: usize

The maximum number of operations allowed to execute concurrently when in HalfOpen state.

operation_timeout: Option<Duration>

Optional timeout for individual operations executed through the circuit breaker.

sliding_window_size: usize

The size of the sliding window used for calculating failure rates.

error_predicate: Option<ErrorPredicate>

An optional predicate to determine if a specific DecrustError should be considered a failure. If None, all Err results are considered failures.

metrics_window_size: usize

The size of the history window for detailed metrics (not fully implemented in this version).

track_metrics: bool

Whether to track detailed metrics.

slow_call_duration_threshold: Option<Duration>

Threshold for an operation to be considered a “slow call”.

slow_call_rate_threshold: Option<f64>

Rate of slow calls (0.0 to 1.0) in the window that can cause the circuit to open.

circuit_breaker_threshold: u32

Number of consecutive failures before opening the circuit breaker.

circuit_breaker_cooldown: Duration

Duration the circuit breaker stays open after tripping.
