zio.managed

package zio.managed

The Managed library provides the ZManaged data type for backward compatibility after the introduction of scopes. For the best experience, import zio.managed._ to get access to extension methods on ZIO data types that convert to and from ZManaged values. This will give you the smoothest possible experience until you are able to upgrade to using scopes directly.

A Reservation[-R, +E, +A] encapsulates resource acquisition and disposal without specifying when or how that resource might be used.

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.

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.
