Struct CompactionCircuitBreaker 

pub struct CompactionCircuitBreaker { /* private fields */ }

Circuit breaker that gates compaction calls after repeated failures.

When consecutive compaction failures reach the configured threshold, the breaker opens and all proactive compaction is skipped for the remainder of the run. Reactive compaction (triggered by a provider context overflow error) is still attempted.

Implementations

impl CompactionCircuitBreaker

pub fn new(threshold: u32) -> Self

Creates a new breaker with the given failure threshold.

pub fn record_success(&mut self)

Records a successful compaction, resetting the failure count and closing the breaker.

pub fn record_failure(&mut self) -> bool

Records a failed compaction. If the failure count reaches the threshold, the breaker opens. Returns true when the breaker transitions from closed to open (so the caller can emit an event).

pub fn is_open(&self) -> bool

Returns true when the breaker is open and proactive compaction should be skipped.

pub fn consecutive_failures(&self) -> u32

Returns the number of consecutive failures recorded so far.
