ghc-abstract-deque

Abstract, parameterized interface to mutable Deques

An abstract interface to highly-parameterizable queues/deques. Background: There exists a feature space for queues that extends between: * simple, single-ended, non-concurrent, bounded queues * double-ended, threadsafe, growable queues ... with important points inbetween (such as the queues used for work-stealing). This package includes an interface for Deques that allows the programmer to use a single API for all of the above, while using the type-system to select an efficient implementation given the requirements (using type families). This package also includes a simple reference implementation based on 'IORef' and "Data.Sequence".
