Expand description

Redis Pub/Sub 跨实例失效总线

复用既有 Redis 连接管理(自动重连),Pub/Sub 专用连接。 消息序列化为 ≤1KB JSON,跳过本实例 instance_id 避免自回环。

Implementations§

Source§

impl RedisPubSubInvalidationBus

Source

pub fn new(client: ConnectionManager, instance_id: impl Into<String>) -> Self

Source

pub fn instance_id(&self) -> &str

获取本实例 ID

Source

pub fn push_received(&self, message: InvalidationMessage)
