AddOrUpdateSlice 添加或更新切片中的元素

func Chunk

func Chunk[T any](slice []T, size int) [][]T

Chunk 将切片分割成指定大小的块

func Contains

func Contains[T comparable](slice []T, item T) bool

Contains 检查切片是否包含指定元素

func Filter

func Filter[T any](objs []T, filter func(obj T) bool) []T

Filter 过滤切片，返回满足条件的元素

func FilterMap
