## skiplist(跳表)

### 接口

```golang

func Default() SkipList

func New(c Compare, maxHeight int) SkipList

/// skip_list.go

type SkipList interface {

	Insert(k, v interface{}) error /// nil | `ErrKeyAlreadyExist`.

	InsertForce(k, v interface{})  /// if exist already,update its `v`.

	Erase(k interface{}) error     /// nil | `ErrKeyNotExist`,most of scenario you can ignore it.

	Find(k interface{}) (v interface{}, exist bool)

	Clear()

	Size() int

	Empty() bool

	Min() (k, v interface{}) /// if Empty(),return nil,nil

	Max() (k, v interface{}) /// if Empty(),return nil,nil

	SkipListIterator

}

type SkipListIterator interface {

	Begin() Iterator /// minimum,or nil if Empty()

	End() Iterator   /// same as nil

}

/// iterator.go

type Iterator interface {

	Next() Iterator /// return's key is bigger than caller's,or nil if not exist

	Key() interface{}

	Value() interface{}

}

```

简单示例看eg/basic.go，详细请看源码以及对应test。

### 注意

* 迭代器按C++ STL设计，插入/删除后迭代器失效。

### TODO

* vargrind

* benchmark
