Returns a task that performs all evaluation asynchronously.
'Catches' exceptions in the given task and returns them as values.
Ensures the result of this Task satisfies the given predicate, or fails with the given value.
Calls attempt and handles some exceptions using the given partial
function, calling Task.now on the result.
Calls attempt and handles some exceptions using the given partial
function, calling Task.now on the result. Any nonmatching exceptions
are reraised.

Returns a new Task in which f is scheduled to be run on completion.
Returns a new Task in which f is scheduled to be run on completion.
This would typically be used to release any resources acquired by this
Task.
Runs this Task, and if it fails with an exception, runs t2.
Runs this Task, and if it fails with an exception, runs t2.
This is rather coarse-grained. Use attempt, handle, and
flatMap for more fine grained control of exception handling.
Returns a Task that, when run, races evaluation of this and t,
and returns the result of whichever completes first.
Returns a Task that, when run, races evaluation of this and t,
and returns the result of whichever completes first. The losing task
continues to execute in the background though its result will be sent
nowhere.
Create a Task that will evaluate a after at least the given delay.
A Task which returns a TimeoutException after timeout,
and attempts to cancel the running computation.
Like run, but returns exceptions as values.
Like unsafeRunFor, but returns exceptions as values.
Like unsafeRunFor, but returns exceptions as values. Both TimeoutException
and other exceptions will be folded into the same Throwable.
Run this Task and block until its result is available.
Run this Task and block until its result is available. This will
throw any exceptions generated by the Task. To return exceptions
in an Either, use unsafeAttemptRun.
Run this computation to obtain either a result or an exception, then invoke the given callback.
Run this computation to obtain either a result or an exception, then
invoke the given callback. Any pure, non-asynchronous computation at the
head of this Future will be forced in the calling thread. At the first
Async encountered, control is transferred to whatever thread backs the
Async and this function returns immediately.
Run this computation and return the result as a standard library Future.
Run this computation and return the result as a standard library Future.
Like unsafeRunAsync but returns a standard library Future instead of requiring
a callback.
Run this Task and block until its result is available, or until
timeout has elapsed, at which point a TimeoutException
will be thrown and the Future will attempt to be canceled.
