final class FiberRef[A] extends Serializable
Fiber's counterpart for Java's ThreadLocal
. Value is automatically propagated
to child on fork and merged back in after joining child.
for { fiberRef <- FiberRef.make("Hello world!") child <- fiberRef.set("Hi!).fork result <- child.join } yield result
result
will be equal to "Hi!" as changes done by child were merged on join.
