Purpose

Types for dealing with slices of 'ByteArray' and 'MutableByteArray'. These are never supposed to introduce overhead. Rather, they exist to clarify intent in type signatures.

receive ::
     Resource -- ^ Some scarce resource
  -> MutableByteArray RealWorld -- ^ Buffer
  -> Int -- ^ Offset
  -> Int -- ^ Length
  -> IO ()

With this library, we instead write

receive ::
     Resource -- ^ Some scarce resource
  -> MutableBytes RealWorld -- ^ Buffer
  -> IO ()

The combination of the worker-wrapper transformation and inlining means that we can expect these two to end up generating the same code in most situations.
