Methods

impl Client

pub async fn connect<A>(addr: A) -> Result<Client, Error> where
    A: ToSocketAddrs, 

连接到消息总线

pub fn node_id(&self) -> NodeId

获取当前节点id

pub async fn register_service<N>(&'_ self, name: N, id: LocalServiceId) where
    N: Into<String>, 

注册服务

pub async fn subscribe<T, F, R>(&'_ self, handler: F) -> SubscribeId where
    F: FnMut(T) -> R + Send + 'static,
    R: Future<Output = ()> + Send + 'static,
    T: Topic, 

订阅消息 如果重复订阅，则会按订阅顺序依次触发回调函数，并不会增加数据传输流量

pub async fn subscribe_with_topic<T, F, R>(
    &'_ self,
    topic: &'_ str,
    handler: F
) -> SubscribeId where
    F: FnMut(T) -> R + Send + 'static,
    R: Future<Output = ()> + Send + 'static,
    T: Topic, 

订阅指定主题的消息

pub async fn unsubscribe(&'_ self, id: SubscribeId)

取消订阅消息
