This repository contains splay tree implementation.

This implementation does not allow duplicate elements in the tree, so it may be used as set data type.

Usage.

    type ComparableString string

    func (sv ComparableString) CompareTo(i interface{}) int {
        if ts, ok := i.(ComparableString); ok {
            return strings.Compare(string(sv), string(ts))
        }

        return -1
    }

    ...

    tree := splaytree.NewSplayTree()
    tree.Insert(ComparableString("A"))
    tree.Insert(ComparableString("B"))
    tree.Insert(ComparableString("C"))
    ...

    if tree.Has(ComparableString("C")) {
        ...
    }
    ...

    if tree.Remove(ComparableString("B")) {
        // B was removed
        ...
    }

    tree.Traverse(func(c splaytree.Comparable, level int) bool {
        // level shows how deep in the tree the value is, root has value 0

        return canContinueTraverse // false to stop traverse
    })
