Types

type Trie

type Trie[V any] struct {
	// contains filtered or unexported fields
}

func New

func New[V any]() *Trie[V]

func (*Trie[V]) Delete

func (t *Trie[V]) Delete(k string)

删除有两种方法, 这里先选择第1种，后面有时间再压测下第二种效率如何 1.记录rune和节点，删除这个节点。如果是子节点，再回溯删除 2.声明一个parent指针，不记录过程节点，直接p = n.parent; p != nil; p=p.parent 回溯删除

func (*Trie[V]) Get

func (t *Trie[V]) Get(k string) (v V)

func (*Trie[V]) HasPrefix

func (t *Trie[V]) HasPrefix(k string) bool

func (*Trie[V]) Len

func (t *Trie[V]) Len() int

func (*Trie[V]) Set

func (t *Trie[V]) Set(k string, v V)

func (*Trie[V]) Swap

func (t *Trie[V]) Swap(k string, v V) (prev V, replaced bool)

func (*Trie[V]) TryGet

func (t *Trie[V]) TryGet(k string) (v V, found bool)
