    Returns an effect that forks this effect into its own separate fiber, returning the fiber immediately, without waiting for it to begin executing the effect.

    You can use the fork method whenever you want to execute an effect in a new fiber, concurrently and without "blocking" the fiber executing other effects. Using fibers can be tricky, so instead of using this method directly, consider other higher-level methods, such as raceWith, zipPar, and so forth.

    The fiber returned by this method has methods to interrupt the fiber and to wait for it to finish executing the effect. See zio.Fiber for more information.

    Whenever you use this method to launch a new fiber, the new fiber is attached to the parent fiber's scope. This means when the parent fiber terminates, the child fiber will be terminated as well, ensuring that no fibers leak. This behavior is called "auto supervision", and if this behavior is not desired, you may use the forkDaemon or forkIn methods.

    Returns an effect that races this effect with the specified effect, returning the first successful A from the faster side. If one effect succeeds, the other will be interrupted. If neither succeeds, then the effect will fail with some error.

    Note that both effects are disconnected before being raced. This means that interruption of the loser will always be performed in the background. This is a change in behavior compared to ZIO 2.0.

    Returns an effect that will timeout this effect, returning None if the timeout elapses before the effect has produced a value; and returning Some of the produced value otherwise.

    If the timeout elapses without producing a value, the running effect will be safely interrupted.

    WARNING: The effect returned by this method will not itself return until the underlying effect is actually interrupted. This leads to more predictable resource utilization. If early return is desired, then instead of using effect.timeout(d), use effect.disconnect.timeout(d), which first disconnects the effect's interruption signal before performing the timeout, resulting in earliest possible return, before an underlying effect has been successfully interrupted.
