Not in Unity's public API, or in an assembly the coverage doesn't count.
In Tassix

A value made of numbers (vectors, rects), edited in a numeric field per part, in lines of fieldsByLine (each line padded with a spacer when it holds fewer than three). A part's change makes the whole value's (after the part's own ChangeEvent has bubbled up).
