impl TransportLease

Source

pub async fn cancelled(&self)

业务作用:让连接、排队和流消费等待响应同一 owner 的关闭。

参数说明:无。

返回:owner 最终关闭后完成,不授予调用方关闭 owner 的权限。

Source

pub fn spawn( self, deadline: Instant, future: impl Future<Output = ()> + Send + 'static, ) -> Result<AbortHandle>

业务作用:将有限传输任务交给 owner 接管,等待者丢弃不造成后台任务失去归属。

参数说明:

  • deadline:是绝对期限
  • future:是不超过该期限的连接或正文处理。

返回:只控制本任务的终止句柄;关闭时禁止启动,任务结束自动归还容量。
