Functions

func Contains

func Contains[T comparable](collection []T, element T) bool

Contains returns true if an element is present in a collection. Deprecated: use `slice.Contains` which import from `golang.org/x/exp/slices` instead

func FromJSONBase64

func FromJSONBase64(encodeStr string, obj interface{}) error

FromJSONBase64 decode encodeStr using base64, and then use json to convert to obj. Deprecated: use encoding.Base64Decode instead

func Paginate

func Paginate(total, perPage, page int) (begin, end int)

Paginate this function implements the paging of List, inputting the total number of data (usually the length of Slice), the number of each page, and the page number. The function guarantees that Begin and End do not exceed the total number of data.

If input perPage is less than 1, it will be set as DefaultPerPage. If input page is less than 1, it will be set as DefaultPage.

Returns the start and end position of the pagination.

func ToJSONBase64

func ToJSONBase64(obj interface{}) (string, error)

ToJSONBase64 convert obj to json string, and then encode it with base64. Deprecated: use encoding.Base64Encode instead
