Struct SemanticsScrollBy 

pub struct SemanticsScrollBy { /* private fields */ }

What a container does when a screen reader pages it, e.g. TalkBack’s scroll forward action or an accesskit scroll down. The two deltas are in layout pixels; the answer says whether anything moved.

This is Compose’s SemanticsActions.ScrollBy.
