我应该使用 Clojure 的手指树做什么？
Clojure 的新 contrib 库组有一个 手指树 库。 Clojure 中手指树的用例有哪些？何时应该使用手指树来代替 clojure 的其他持久数据结构之一：向量、集合、映射、持久队列等。
Clojure 的乐趣 提到手指树可用于需要廉价插入和删除的索引集合。它们也被描述为“数据结构的瑞士军刀”。非常感谢这样的例子。
Clojure's new contrib library group has a finger tree library. What are the use cases for finger trees in clojure? When should finger trees be used instead of one of clojure's other peristent data strucures: vectors, sets, maps, persistentqueues, etc.
The Joy of Clojure mentions that Finger trees can be used for indexed collections where cheap insertions and deletions are required. They have also been described as the "swiss army knife of data structures." Examples of this would be very much appreciated.

Ralf Hinze 和 Ross 的论文中描述了 2-3 个手指树帕特森。它们不仅提供了数据结构本身的完整描述，还提供了如何在 Haskell 中使用它的几个示例。他们描述的大多数功能已经在 Clojure 库中提供，但文档还没有。
本周末我将在 Clojure Conj 上介绍 Clojure 手指树。
更新： 现在有一些示例显示在 http:// github.com/clojure/data.finger-tree#readme

2-3 finger trees are described in a paper by Ralf Hinze and Ross Paterson. They provide not only a complete description of the data structure itself, but several examples of how it can be used ...in Haskell. Most of the features they describe are already available in the Clojure library, but the documentation simply isn't there yet.
I'll be introducing Clojure finger trees at Clojure Conj this weekend.
Update: There are now some examples shown at http://github.com/clojure/data.finger-tree#readme
