trait Fiber[+E, +A] extends AnyRef
A fiber is a lightweight thread of execution that never consumes more than a
whole thread (but may consume much less, depending on contention). Fibers are
spawned by forking IO
actions, which, conceptually at least, runs them
concurrently with the parent IO
action.
Fibers can be joined, yielding their result other fibers, or interrupted, which terminates the fiber with a runtime error.

Abstract Value Members

abstract
def
await: UIO[Exit[E, A]]
Awaits the fiber, which suspends the awaiting fiber until the result of the fiber has been determined.
-
abstract
def
inheritFiberRefs: UIO[Unit]
Inherits values from all FiberRef instances into current fiber.
Inherits values from all FiberRef instances into current fiber. This will resume immediately.
-
abstract
def
interrupt: UIO[Exit[E, A]]
Interrupts the fiber with no specified reason.
Interrupts the fiber with no specified reason. If the fiber has already terminated, either successfully or with error, this will resume immediately. Otherwise, it will resume when the fiber terminates.
-
abstract
def
poll: UIO[Option[Exit[E, A]]]
Tentatively observes the fiber, but returns immediately if it is not already done.

Joins the fiber, which suspends the joining fiber until the result of the fiber has been determined.
Joins the fiber, which suspends the joining fiber until the result of the fiber has been determined. Attempting to join a fiber that has errored will result in a catchable error, _if_ that error does not result from interruption.
