Struct CircuitBreaker 

pub struct CircuitBreaker<E> { /* private fields */ }

Circuit breaker configuration + (after build) live state.

Build with CircuitBreaker::consecutive_failures or CircuitBreaker::failure_ratio. record_when (optional) decides which operation errors count as breaker faults; by default every error counts.

Implementations

impl<E> CircuitBreaker<E>

pub fn consecutive_failures(n: u32) -> Self

Trip after n consecutive failures.

pub fn failure_ratio() -> Self

Trip when the failure ratio over a sampling window is exceeded.

pub fn failure_ratio_value(self, ratio: f64) -> Self

pub fn ratio(self, ratio: f64) -> Self

Alias matching the spec’s fluent name .failure_ratio(0.5).

pub fn minimum_throughput(self, n: u32) -> Self

pub fn sampling_window(self, d: Duration) -> Self

pub fn open_for(self, d: Duration) -> Self

pub fn half_open_max_calls(self, n: u32) -> Self

pub fn record_when( self, pred: impl Fn(&E) -> bool + Send + Sync + 'static, ) -> Self
