pkg/tablecodec/tablecodec.go:747–759

CutIndexKeyTo cuts encoded index key into colIDs to bytes slices. The caller should prepare the memory of the result values.

// CutIndexKeyNew cuts encoded index key into colIDs to bytes slices.
// The returned value b is the remaining bytes of the key which would be empty if it is unique index or handle data
