type SyncMap[K comparable, V any] struct {
	Mi sync.Map
}

泛型包装器，使用sync.Map实现

func NewSyncMap[K comparable, V any]() *SyncMap[K, V]

初始化

func (sm *SyncMap[K, V]) Clear()

清空

func (sm *SyncMap[K, V]) CompareAndSwap(key K, old, new V) bool

CompareAndSwap 如果键对应的值等于old，则替换为new

func (sm *SyncMap[K, V]) Delete(key K)

Delete 删除键对应的值

func (sm *SyncMap[K, V]) Len() int

大小

func (sm *SyncMap[K, V]) Load(key K) (V, bool)

Load 加载键对应的值

func (sm *SyncMap[K, V]) LoadAndDelete(key K) (V, bool)

LoadAndDelete 加载并删除键对应的值

func (sm *SyncMap[K, V]) LoadOrStore(key K, value V) (actual V, loaded bool)

LoadOrStore 如果键不存在，则存储键值对；如果键已存在，则返回已存在的值

func (sm *SyncMap[K, V]) Range(f func(K, V) bool)

Range 遍历映射

func (sm *SyncMap[K, V]) Store(key K, value V)

Store 存储键值对

func (sm *SyncMap[K, V]) Swap(key K, value V) (old V, loaded bool)

Swap 替换键对应的值
