Summary:
`Values` is a wrapper to story an array of YGValue's as CompactValues.
From https://github.com/facebook/yoga/issues/1174 we see a warning `Wdeprecated-copy` beacuse a user-defined copy constructor is not present, but a user-defined asignment operator is (the defaulted one). This adds an explicitly defaulted copy contructor which should silence the warning I think.
