pub struct CacheCoherenceProtocol { /* private fields */ }

缓存一致性协议

Implementations

impl CacheCoherenceProtocol

pub fn new( instance_id: String, strategy: ConsistencyStrategy, broadcaster: Arc<dyn InvalidationBroadcaster>, ) -> Self

创建新的一致性协议实例

pub fn state(&self, key: &str) -> MesiState

获取缓存行状态

pub fn read(&self, key: &str, other_instances_have: bool) -> MesiState

读操作（触发状态转换：Invalid→Exclusive/Shared）

pub fn write(&self, key: &str) -> Result<MesiState, CoherenceError>

写操作（触发状态转换：→Modified，广播失效）

pub fn handle_invalidation(&self, event: &InvalidationEvent)

处理收到的失效广播（→Invalid）

pub fn metrics(&self) -> CoherenceMetrics

获取指标快照

pub fn strategy(&self) -> ConsistencyStrategy

获取写策略
