From Task

object_pool_index size_t object_pool_index;: Reserved index field which ensures that any Task derivative can be used with ObjectPool. That comes at minor cost of one unused size_t per Task instance if not needed which is not a problem.
fiber WorkerFiber fiber;: Fiber this task executes in
getThis Task getThis()
assignTo void assignTo(WorkerFiber fiber, void delegate() entry_point): Assigns the task to a fiber. In most cases you need to use Scheduler.schedule instead.
suspend void suspend(): Suspends execution of this task.
resume void resume(): Resumes execution of this task. If task has not been started yet, starts it.
terminationHook void terminationHook(void delegate() hook): Registers a termination hook that will be executed when the Task is killed.
removeTerminationHook void removeTerminationHook(void delegate() hook): Unregisters a termination hook that would be executed when the Task is killed.
suspended bool suspended()
finished bool finished()
kill void kill(istring file, int line): Forces abnormal termination for the task by throwing special exception instance.
recycle void recycle(): Method that will be run by scheduler when task finishes. Must be overridden by specific task class to reset reusable resources.
run void run(): Method that must be overridden in actual application/library task classes to provide entry point.
entryPoint bool entryPoint(): Internal wrapper around this.run() which is used as primary fiber entry point and ensures any uncaught exception propagates to the context that has started this task.
