Enum BreakerState 

pub enum BreakerState {
    Closed = 0,
    Open = 1,
    HalfOpen = 2,
}

Three-state circuit breaker (RFC 0018 §4.2). Stored as a u8 in the health record so the whole record is lock-free.

Variants

Closed = 0

Normal — in rotation.

Open = 1

Removed from rotation for a cooldown after N consecutive failures.

HalfOpen = 2

Eligible for exactly one probe; success re-closes, failure re-opens.
