Enum CircuitState 

#[repr(u8)]
pub enum CircuitState {
    Closed = 0,
    Open = 1,
    HalfOpen = 2,
}

Circuit breaker states.

The circuit breaker transitions between these states based on request success/failure patterns.

Variants

Closed = 0

Normal operation, requests are allowed. Failures are counted, and if they exceed the threshold, the circuit transitions to Open.

Open = 1

Blocking requests due to failures. All requests are rejected immediately with a ResourceExhausted error. After reset_timeout elapses, transitions to HalfOpen.

HalfOpen = 2

Testing if the service has recovered. Allows a limited number of test requests. If successful, transitions to Closed; if failed, transitions back to Open.

Trait Implementations

impl Clone for CircuitState

fn clone(&self) -> CircuitState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CircuitState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for CircuitState

fn eq(&self, other: &CircuitState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
