Creates new ZManaged from a ZIO value that uses a ReleaseMap and returns a resource and a finalizer.
The correct usage of this constructor consists of: - Properly registering a finalizer in the ReleaseMap as part of the ZIO value; - Managing interruption safety - take care to use ZIO.uninterruptible or ZIO.uninterruptibleMask to verify that the finalizer is registered in the ReleaseMap after acquiring the value; - Returning the finalizer returned from ReleaseMap#add. This is important to prevent double-finalization.

def runtime[R]: ZManaged[R, Nothing, Runtime[R]]
Returns an ZManaged that accesses the runtime, which can be used to (unsafely) execute tasks.
Returns an ZManaged that accesses the runtime, which can be used to (unsafely) execute tasks. This is useful for integration with legacy code that must call back into ZIO code.
def sandbox[R, E, A](v: ZManaged[R, E, A]): ZManaged[R, Cause[E], A]
lazy val scope: Managed[Nothing, Scope]
Creates a scope in which resources can be safely allocated into together with a release action.
def service[A](implicit arg0: zio.Tag[A]): ZManaged[Has[A], Nothing, A]
Accesses the specified service in the environment of the effect.
def serviceAt[Service]: ServiceAtPartiallyApplied[Service]
Accesses the service corresponding to the specified key in the environment.
def serviceWith[Service]: ServiceWithPartiallyApplied[Service]
Effectfully accesses the specified service in the environment of the effect.
Effectfully accesses the specified service in the environment of the effect.
```
def foo(int: Int) = ZManaged.serviceWith[Foo](_.foo(int))
```
def serviceWithManaged[Service]: ServiceWithManagedPartiallyApplied[Service]
Effectfully accesses the specified managed service in the environment of the effect .
Effectfully accesses the specified managed service in the environment of the effect .

def shift(executor: => Executor): ZManaged[Any, Nothing, Unit]
Returns a managed effect that describes shifting to the specified executor as the acquire action with no release action.
def some[A](a: => A): UManaged[Option[A]]
Returns an effect with the optional value.
def succeed[A](r: => A): ZManaged[Any, Nothing, A]
Lifts a lazy, pure value into a Managed.
def suspend[R, E, A](zManaged: => ZManaged[R, E, A]): ZManaged[R, E, A]
Returns a lazily constructed Managed.
def switchable[R, E, A]: ZManaged[R, Nothing, (ZManaged[R, E, A]) => ZIO[R, E, A]]
Returns a ZManaged value that represents a managed resource that can be safely swapped within the scope of the ZManaged.
Returns a ZManaged value that represents a managed resource that can be safely swapped within the scope of the ZManaged. The function provided inside the ZManaged can be used to switch the resource currently in use.
When the resource is switched, the finalizer for the previous finalizer will be executed uninterruptibly. If the effect executing inside the ZManaged#use is interrupted, the finalizer for the resource currently in use is guaranteed to execute.
This constructor can be used to create an expressive control flow that uses several instances of a managed resource. For example:
```
def makeWriter: Task[FileWriter]
trait FileWriter {
  def write(data: Int): Task[Unit]
  def close: UIO[Unit]
}

val elements = List(1, 2, 3, 4)
val writingProgram =
  ZManaged.switchable[Any, Throwable, FileWriter].use { switchWriter =>
    ZIO.foreachDiscard(elements) { element =>
      for {
        writer <- switchWriter(makeWriter.toManaged(_.close))
        _      <- writer.write(element)
      } yield ()
    }
  }
```
