Functions

func Append

func Append[T any](data map[string]T, append map[string]T)

Append 将一个map合并到另一个map中

func BuildKeys

func BuildKeys[K any](mapData interface{}, keyType K) []K

func BuildMapByKey

func BuildMapByKey(mapList []map[string]interface{}, mapKey string) map[interface{}]interface{}

func BuildMapByStringKey

func BuildMapByStringKey(mapList []map[string]interface{}, mapKey string) map[string]interface{}

func BuildSliceByStringKey
