returns
UIO[Unit]
abstract def interruptAs(fiberId: Id): UIO[Exit[E, A]]

returns
UIO[Exit, E, A]]
abstract def poll: UIO[Option[Exit[E, A]]]

Tentatively observes the fiber, but returns immediately if it is not already done.

returns
UIO[Option[Exit, E, A]]]
abstract def status: UIO[Status]

abstract def trace: UIO[Option[ZTrace]]

The trace of the fiber.
