    nuu: FLValue,
) -> FLSliceResult
Expand description

Returns JSON that encodes the changes to turn the value old into nuu. (The format is documented in Fleece.md, but you should treat it as a black box.) @param old A value that’s typically the old/original state of some data. @param nuu A value that’s typically the new/changed state of the old data. @return JSON data representing the changes from old to nuu, or NULL on (extremely unlikely) failure.
