package Task
Transforms a Task into a Coeval that tries to
execute the source synchronously, returning either Right(value)
in case a value is available immediately, or Left(future) in case
we have an asynchronous boundary.
Returns a task that waits for the specified timespan before
executing and mirroring the result of the source.
Returns a task that waits for the specified timespan before
executing and mirroring the result of the source.
Returns a task that waits for the specified trigger to succeed
before mirroring the result of the source.
Returns a task that waits for the specified trigger to succeed
before mirroring the result of the source.
If the trigger ends in error, then the resulting task will also
end in error.
Returns a task that executes the source immediately on runAsync,
but before emitting the onSuccess result for the specified
duration.
Returns a task that executes the source immediately on runAsync,
but before emitting the onSuccess result for the specified
duration.
Note that if an error happens, then it is streamed immediately with no delay.

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.
The returned Task completes when both the source and the
task returned by f complete.
Returns a failed projection of this task.
Returns a failed projection of this task.
The failed projection is a future holding a value of type
Throwable, emitting a value which is the throwable of the
original task in case the original task fails, otherwise if the
source succeeds, then it fails with a NoSuchElementException.
Creates a new Task by applying a function to the successful result of the source Task, and returns a task equivalent to the result of the function.
Creates a new Task by applying a function to the successful result of the source Task, and returns a task equivalent to the result of the function.
Given a source Task that emits another Task, this function flattens the result, returning a Task equivalent to the emitted Task by the source.

Returns a new Task that applies the mapping function to the element emitted by the source.
Returns a new Task that applies the mapping function to the element emitted by the source.
Creates a new Task that will expose any triggered error from the source.

Memoizes the result on the computation and reuses it on subsequent
invocations of runAsync.

Creates a new task that in case of error will retry executing the source again and again, until it succeeds.
Creates a new task that in case of error will retry executing the source again and again, until it succeeds.
In case of continuous failure the total number of executions
will be maxRetries + 1.

Returns a Task that mirrors the source Task but that triggers a
TimeoutException in case the given duration passes without the
task emitting any item.

Converts a Task to an org.reactivestreams.Publisher that
emits a single item on success, or just the error on failure.

Constructs a lazy Task instance.
This type can be used for "lazy" values. In some sense it is equivalent to using a Function0 value.
