MutableNoClose

Prepend release action to existing

Either an action in F or a pure function used to extract the A from the InnerResource

The effect in the Left branch will be performed interruptibly, it is not afforded the same kind of safety as acquire and release actions when F is an effect type that supports interruption/cancellation.

When F is Identity, it doesn't matter whether the output is a Left or Right branch.

When consuming the output of extract you can use _.fold(identity, F.pure) to convert the Either to F[B]

The action in F used to release, close or deallocate the resource after it has been acquired and used through Lifecycle.SyntaxUse#use.

Wrap acquire action of this resource in another effect, e.g. for logging purposes

Wrap release action of this resource in another effect, e.g. for logging purposes
