Allocate

Deconstruct Resource into an A and a release handler. The release action must always be called, if never called, then the resource A will leak. The release step is already made NonCancellable to guarantee correct invocation like Resource or bracketCase, and it will automatically rethrow, and compose, the exceptions as needed.

Create a resource value of B from a resource A by mapping f.

Composes two Resources together by zipping them in parallel, by running both their acquire handlers in parallel, and both release handlers in parallel.

Useful for setting up/configuring an acquired resource

Use the created resource When done will run all finalizers

Combines two independent resource values with the provided map function, returning the resulting immutable Resource value. The finalizers run in order of left to right by using flatMap under the hood, but zip provides a nicer syntax for combining values that don't depend on each-other.
