Struct CircuitBreakerWrapper 

Source 
pub struct CircuitBreakerWrapper { /* private fields */ }
Expand description

Thread-safe circuit breaker that tracks failures and short-circuits calls when a provider is unhealthy.

State transitions: Closed -> (failures >= threshold) -> Open -> (wait period elapsed) -> HalfOpen -> (probe succeeds) -> Closed (or probe fails -> back to Open).

Implementations§

Source§

impl CircuitBreakerWrapper

Source

pub fn new(config: CircuitBreakerConfig) -> Self

Create a new circuit breaker with the given configuration.

Source

pub async fn call<F, Fut, T>(&self, f: F) -> Result<T>
where F: FnOnce() -> Fut, Fut: Future<Output = Result<T>>,

Execute f through the circuit breaker.

Returns RuntimeError::Unavailable immediately when the breaker is open. In the half-open state only a single probe call is allowed; concurrent callers receive Unavailable until the probe completes.
