Fiber

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.

Fork-Join Identity: fork >=> join = id

for {
  fiber1 <- io1.fork
  fiber2 <- io2.fork
  _      <- fiber1.interrupt(e)
  a      <- fiber2.join
} yield a

Self Type: Fiber[E, A]

Linear Supertypes

AnyRef, Any

Abstract Value Members

abstract def await: IO[Nothing, Exit[E, A]]

Awaits the fiber, which suspends the awaiting fiber until the result of the fiber has been determined.
abstract def interrupt: IO[Nothing, 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 completes.
abstract def poll: IO[Nothing, 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.

final def zip[E1 >: E, B](that: ⇒ Fiber[E1, B]): Fiber[E1, (A, B)]

Zips this fiber and the specified fiber togther, producing a tuple of their output.
final def zipWith[E1 >: E, B, C](that: ⇒ Fiber[E1, B])(f: (A, B) ⇒ C): Fiber[E1, C]

Zips this fiber with the specified fiber, combining their results using the specified combiner function.
Zips this fiber with the specified fiber, combining their results using the specified combiner function. Both joins and interruptions are performed in sequential order from left to right.
