Expand description

The traits exposed by this crate.

Structs

  • BlockingHandle
    A framework agnostic BlockingHandle type. This is returned by SpawnBlocking. Await this handle for the output of the task. As opposed to a JoinHandle, you can’t cancel a blocking task once it has started running. If you drop this after the task starts running, it will just detach and let the task run in the background.
  • JoinHandle
    A framework agnostic JoinHandle type. Cancels the future on dropping the handle. You can call detach to leave the future running when dropping the handle.
  • Timeout
    A timeout returned by TimerExt::timeout.
  • TimeoutError
    An error value given when a function times out.
  • YieldNowFut
    Future returned by YieldNow::yield_now.

Traits

  • LocalSpawnHandle
    This is similar to SpawnHandle except that it allows spawning !Send futures. Please see the docs on SpawnHandle.
  • LocalSpawnHandleExt
    Lets you spawn a !Send future and get a JoinHandle to await the output of a future.
  • SpawnBlocking
    Indicate the executor can provide a threadpool for blocking operations. There is two methods of this trait. One of them requires boxing the closure and the other is not object safe.
  • SpawnHandle
    Lets you spawn and get a JoinHandle to await the output of a future.
  • SpawnHandleExt
    Convenience trait for passing in a generic future to SpawnHandle. Much akin to Spawn and SpawnExt in the futures library.
  • Timer
    Represents the fact that an executor has timer functionality.
  • TimerExt
    An extension trait on Timer for timeouts and clock delays.
  • TokioIo
    Trait indicating that tokio IO can be used with the executor that implements it. Currently this can be enabled through features on TokioCt, TokioTp, AsyncGlobal and AsyncStd.
  • YieldNow
    Trait indicating that tasks can yield to the executor. This put’s the current task at the back of the schedulers queue, giving other tasks a chance to run.
