> Dear ImGui has a special 'ListClipper' class which allows to iterate over the visible 'slots' of a list, so that the code which describes the list UI can skip clipped items early. Not sure if egui has something similar.

An egui ScrollArea can request only visible rows from a callback using show_rows:
