Struct InMemoryCircuitBreakerBackend 

pub struct InMemoryCircuitBreakerBackend { /* private fields */ }

In-process circuit breaker backend backed by a Mutex.

Implementations

impl InMemoryCircuitBreakerBackend

pub fn new() -> Self

Create a new in-memory backend with all counters at zero.

Trait Implementations

impl CircuitBreakerBackend for InMemoryCircuitBreakerBackend

fn increment_failures(&self, _service: &str) -> u32

Increment the consecutive failure count for service and return the new count.

fn reset_failures(&self, _service: &str)

Reset the consecutive failure count for service to zero.

fn get_failures(&self, _service: &str) -> u32

Return the current consecutive failure count for service.

fn set_open_at(&self, _service: &str, at: Instant)

Record the instant at which the circuit was opened for service.

fn clear_open_at(&self, _service: &str)

Clear the open-at timestamp, effectively moving the circuit to Closed or HalfOpen.

fn get_open_at(&self, _service: &str) -> Option<Instant>

Return the instant at which the circuit was opened, or None if it is not open.

impl Default for InMemoryCircuitBreakerBackend

fn default() -> Self

Returns the “default value” for a type.
