Trait AsyncHandle 

pub trait AsyncHandle<T>: Future<Output = Result<T, ()>> + Send {
    // Required methods
    fn is_finished(&self) -> bool;
    fn detach(self);
    fn abort(self);
}

A handle for managing spawned async tasks.

This trait provides methods for waiting for a task’s completion or detaching it to run in the background.

NOTE:

The behavior of dropping a AsyncHandle should be detach, we adopt this behavior because user is more familiar with tokio’s behavior. We don’t want bugs when dropping the task handle unnoticed.

Type Parameters

• T - The return type of the task

Returns

A future that resolves to Ok(T) if the task completed successfully, or Err(()) if the task panics.

Required Methods

fn is_finished(&self) -> bool

Whether a task can be join immediately

fn detach(self)

Detach the task to run in the background without waiting for its result.

After calling this method, the task will continue running until it completes or until its runtime dropped.

fn abort(self)

Abort the task execution, don’t care for it’s result
