ZManagedCpsMonad

class ZManagedCpsMonad[R, E](using x$1: ThrowableAdapter[R, E]) extends CpsTryMonad[[X] =>> ZManaged[R, E, X]]

CpsMonad which encapsulate effects with automatic resource management.

Example of usage:

 asyncRManaged[R] {
     val input = FileChannel.open(inputPath)
     val output = FileChannel.open(outputPath)
     input.transformTo(0,Long.MaxValue,output)
 }
