Snapshot of statistics for a single peer’s circuit breaker.

Fields

state: String

Human-readable current state: "Closed", "Open", or "HalfOpen".

failure_count: u32

Number of failures recorded in the sliding window.

success_count: u32

Number of successes recorded in the sliding window.

consecutive_failures: u32

Current run of consecutive failures (resets on any success).

consecutive_successes: u32

Current run of consecutive successes (only meaningful in HalfOpen).

total_calls: u64

Total calls ever attempted (including rejected ones).

rejected_calls: u64

Calls rejected because the circuit was Open (or HalfOpen at capacity).

last_opened_at: Option<u64>

Timestamp (ms) of the most recent Open transition.

last_closed_at: Option<u64>

Timestamp (ms) of the most recent Closed transition (recovery).
