# CircuitBreakerStateEnum Enum

Enum determining the state of a circuit breaker.

<a id="values"></a>

### Values

<a id="closed"></a>

#### [`CLOSED`](#closed)

The breaker is conducting (requests are passing through).

<a id="half-open"></a>

#### [`HALF_OPEN`](#half-open)

The breaker is in a trial period (to close or open). Note that unlike classic breaker patterns, this is not a state where we are throttling the number of requests, it's a state similar to CLOSED but with different thresholds.

<a id="open"></a>

#### [`OPEN`](#open)

The breaker is tripped (no requests are passing). Breaker will enter half-open state after cooldown period.
