Functions

func DecodeUid added in v0.14.2

func DecodeUid(uid types.Uid) int64

DecodeUid takes an XTEA encrypted Uid and decrypts it into an int64. This is needed for sql compatibility. Tte original int64 values are generated by snowflake which ensures that the top bit is unset.

func EncodeUid added in v0.14.2

func EncodeUid(id int64) types.Uid

EncodeUid applies XTEA encryption to an int64 value. It's the inverse of DecodeUid.

func InitAuthLogicalNames added in v0.15.7

func InitAuthLogicalNames(config json.RawMessage) error

InitAuthLogicalNames initializes authentication mapping "logical handler name":"actual handler name". Logical name must not be empty, actual name could be an empty string.

func RegisterAdapter added in v0.14.2

func RegisterAdapter(a adapter.Adapter)

RegisterAdapter makes a persistence adapter available. If Register is called twice or if the adapter is nil, it panics.

func RegisterAuthScheme

func RegisterAuthScheme(name string, handler auth.AuthHandler)

RegisterAuthScheme registers an authentication scheme handler. The 'name' must be the hardcoded name, NOT the logical name.

func RegisterMediaHandler added in v0.15.2

func RegisterMediaHandler(name string, mh media.Handler)

RegisterMediaHandler saves reference to a media handler (file upload-download handler).

func RegisterValidator added in v0.14.4
