Functions

func DecodeKeysetCursor

func DecodeKeysetCursor[T any](cursor string, keys []string) (map[string]any, error)

func DecodeOffsetCursor

func DecodeOffsetCursor(cursor string) (int, error)

func EncodeKeysetCursor

func EncodeKeysetCursor[T any](node T, keys []string) (string, error)

func EncodeOffsetCursor

func EncodeOffsetCursor(offset int) string

func NewKeysetAdapter

func NewKeysetAdapter[T any](finder KeysetFinder[T]) relay.ApplyCursorsFunc[T]

func NewOffsetAdapter

func NewOffsetAdapter[T any](finder OffsetFinder[T]) relay.ApplyCursorsFunc[T]

NewOffsetAdapter creates a relay.ApplyCursorsFunc from an OffsetFinder. If you want to use `last!=nil&&before==nil`, the finder must implement Counter.

func WrapAES

func WrapAES[T any](next relay.ApplyCursorsFunc[T], encryptionKey []byte) relay.ApplyCursorsFunc[T]

func WrapBase64

func WrapBase64[T any](next relay.ApplyCursorsFunc[T]) relay.ApplyCursorsFunc[T]
