Enum 枚举类型结构体，用于表示具有值和标签的枚举项 T 是可比较的类型

func NewEnum

func NewEnum[T comparable, V any](value T, data V) *Enum[T, V]

NewEnum 创建一个新的枚举实例

type EnumManager

type EnumManager[T comparable, V any] struct {
	// contains filtered or unexported fields
}

EnumManager 枚举管理器结构体，用于管理一组枚举项 T 是可比较的类型

func NewEnums

func NewEnums[T comparable, V any](enums ...*Enum[T, V]) *EnumManager[T, V]

func (*EnumManager[T, V]) GetEnum

func (manager *EnumManager[T, V]) GetEnum(value T) *Enum[T, V]

func (*EnumManager[T, V]) GetEnums
