Abstract Value Members

  1. abstract def available: F[A]

    Returns the number of permits currently available.

    Returns the number of permits currently available. May be out of date the instant after it is retrieved.

  2. abstract def taken: F[A]

    Obtains a snapshot of the currently taken.

    Obtains a snapshot of the currently taken.

    Like available when permits are available but returns the number of permits callers are waiting for when there are no permits available.

  3. abstract def withPermit[B](t: F[B]): F[B]

    Returns an effect that acquires a permit, runs the supplied effect, and then releases the permit.

  4. abstract def withPermitN[B](take: A)(t: F[B]): F[B]

    Returns an effect that acquires a permit, runs the supplied effect, and then releases the permit.
