Enum BreakerState 

pub enum BreakerState {
    Closed,
    Open,
    HalfOpen,
}

The circuit breaker’s state-machine position.

CLOSED --(N consecutive failures)--> OPEN --(recovery_timeout)--> HALF_OPEN
   ^                                   ^                              |
   |                                   +------ any probe fails -------+
   +------------ enough probes succeed ---------------------------------+

Variants

Closed

Calls flow normally.

Open

Calls are rejected to protect a failing backend.

HalfOpen

A limited number of probe calls are allowed to test recovery.
