Implementations

impl EngineBuilder

pub fn provider( self, provider: Arc<dyn Provider>, policy: ResiliencePolicy, priority: i32, ) -> Self

pub fn jitter(self, jitter: Jitter) -> Self

Replaces the backoff jitter source (for deterministic tests).

pub fn cache(self, cache: Arc<dyn Cache>) -> Self

Caches provider answers (and serves them stale if a provider fails).

pub fn cache_policy(self, policy: CachePolicy) -> Self

pub fn clock(self, clock: Clock) -> Self

Replaces the clock (for deterministic cache-expiry tests).

pub fn build(self) -> Engine
