Struct CircuitBreaker 

pub struct CircuitBreaker { /* private fields */ }

Failure isolation state for a fallible dependency.

Implementations

impl CircuitBreaker

pub fn new( failure_threshold: u32, recovery_threshold: u32, cooldown: Duration, ) -> Self

Creates a circuit breaker with caller-defined thresholds and cooldown.

pub fn default_breaker() -> Self

Creates the standard kernel circuit breaker.

pub fn state(&self) -> CircuitState

Returns the current circuit state.

pub fn record_success(&mut self)

Records a successful dependency call.

pub fn record_failure(&mut self)

Records a failed dependency call.

pub fn should_allow(&mut self) -> bool

Returns whether a dependency call should proceed.

Side effect: if the breaker is Open and the cooldown has elapsed, this transitions the state to HalfOpen.

pub fn reset(&mut self)

Forces the circuit into its initial closed state.
