final class ZManaged[-R, +E, +A] extends Serializable
A ZManaged[R, E, A]
is a managed resource of type A
, which may be used by
invoking the use
method of the resource. The resource will be automatically
acquired before the resource is used, and automatically released after the
resource is used.
Resources do not survive the scope of use
, meaning that if you attempt to
capture the resource, leak it from use
, and then use it after the resource
has been consumed, the resource will not be valid anymore and may fail with
some checked error, as per the type of the functions provided by the resource.

useNow: ZIO[R, E, A]
Runs the acquire and release actions and returns the result of this managed effect.
Runs the acquire and release actions and returns the result of this managed effect. Note that this is only safe if the result of this managed effect is valid outside its scope.

.Modifies this
ZManaged
to provide a canceler that can be used to eagerly execute the finalizer of thisZManaged
. The canceler will run uninterruptibly with an exit value indicating that the effect was interrupted, and if completed will cause the regular finalizer to not run. -

withEarlyReleaseExit(e: Exit[Any, Any]): ZManaged[R, E, (UIO[Any], A)]
A more powerful version of withEarlyRelease that allows specifying an exit value in the event of early release.
