resourcet-pool

resource-pool provides the Pool abstraction, which performs resource allocation. Independently, resourcet provides the Acquire abstraction, which also performs resource allocation, but also plugs into the MonadResource type class. This library provides a way of converting a Pool into an Acquire, if using Acquire functions is easier for your application.

This library exports a single function

poolToAcquire :: Pool a -> Acquire a

which pretty much does what it says on the box.
