Haskell的标准队列包?

问题描述

Haskell是否有标准的队列实现?我看到了几种相当成熟的优先级队列实现，但没有简单的队列. Data.Sequence似乎还可以，但是我认为使用更严格的数据类型可以获得更好的性能.此外，限制操作(即不是双端队列)可以防止错误从错误的一端使队列出队列.

澄清一下，我希望有一个成熟的Haskell实现，最好是在Haskell Platform或Hackage中.

解决方案

Data.Queue在ghc 6.4 [1]中添加到了base中，并在ghc 6.6 [2]中被Data.Sequence包含时弃用了. /p>

摘自6.6发行说明:

[2] https://downloads.haskell.org/~ghc/6.6/docs/html/users_guide/release-6-6.html

Is there a standard queue implementation for Haskell? I see several reasonably mature priority queue implementations, but no simple queues. Data.Sequence seems OK, but I assume we could get better performance with a more restricted datatype. Further, restricting the operations (ie, not a deque) can prevent bugs from dequeuing from the wrong end.

Edit:

To clarify, I was hoping for a mature Haskell implementation, preferably in Haskell Platform or Hackage.

解决方案

Data.Queue was added to base in ghc 6.4 [1] and deprecated in ghc 6.6 [2] when it was subsumed by Data.Sequence.

From the 6.6 release notes:
