Struct CircuitBreaker 

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

Per-(plugin, qname) circuit breaker.

Implementations§

Source§

impl CircuitBreaker

Source

pub fn new(cfg: BreakerConfig) -> Self

Construct a breaker with the given config.

Source

pub fn allow(&self, plugin: &PluginId, qname: &QName) -> bool

Check whether the breaker permits the call. Call before invoking the plugin; if false, fail fast without invocation.

Source

pub fn record_success(&self, plugin: &PluginId, qname: &QName)

Record a successful invocation; resets the failure counter.

Source

pub fn record_failure(&self, plugin: &PluginId, qname: &QName)

Record a failed invocation; trips the breaker if the threshold is met.

Source

pub fn failure_count(&self, plugin: &PluginId, qname: &QName) -> u64

Returns the current consecutive-failure count for diagnostics.
