Struct DisplayEdit 

pub struct DisplayEdit {
    pub old: Range<DisplayPoint>,
    pub new: Range<DisplayPoint>,
}

A display-space edit region: what TabMap::sync would return if a display-space invalidation reader ever appeared. There is none today — the FoldMap re-derives per frame and word wrap is rejected — so sync returns () and downstream caches (line cache, paragraph cache) invalidate off the buffer-space edit they already consume.

If it is ever produced, old ranges the pre-sync snapshot and new the post-sync one, read downstream as a region to invalidate rather than a description of the change. It stays row-preserving: within one line old and new share their row and differ only in cell columns; a line insert/delete shifts whole rows.

Fields

old: Range<DisplayPoint>

Pre-sync display-space range.

new: Range<DisplayPoint>

Post-sync display-space range.
