@JvmName("guarantee") fun <A> Kind<ForIO, A>.~~guarantee~~(finalizer: Kind<ForIO, Unit>): IO<A>
Deprecated: The IO datatype and it’s related type classes will disappear in Arrow 0.13.0. All useful operations are offered directly over suspend functions by Arrow Fx Coroutines. https://arrow-kt.io/docs/fx/async/
Executes the given finalizer when the source is finished, either in success or in error, or if cancelled.
As best practice, it’s not a good idea to release resources via guaranteeCase in polymorphic code.
Prefer bracket for the acquisition and release of resources.
