type TreapForEacher ¶ Uses

type TreapForEacher interface {
    ForEach(func(k, v []byte) bool)
}

TreapForEacher is an interface which allows iteration of a treap in ascending order using a user-supplied callback for each key/value pair. It mainly exists so both mutable and immutable treaps can be atomically committed to the database with the same function.
