Struct potatonet_node::NodeContext

pub struct NodeContext<'a> { /* fields omitted */ }

节点上下文

Methods

impl<'a> NodeContext<'a>

pub fn from(&self) -> Option<ServiceId>

请求或者通知来源服务id

pub fn service_name(&self) -> &str

当前服务名称

pub fn service_id(&self) -> ServiceId

当前服务id

pub fn shutdown_node(&self)

停止节点运行

impl<'a> NodeContext<'a>

pub async fn subscribe_with_topic<'_, '_, T, F, R>(
    &'_ self,
    topic: &'_ str,
    __arg2: F
) -> SubscribeId where
    T: Topic,
    F: FnMut(&NodeContext, T) -> R + Send + 'static,
    R: Future<Output = ()> + Send + 'static, 

订阅指定主题的消息

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

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 unsubscribe<'_>(&'_ self, id: SubscribeId)

取消订阅
