Struct SemanticsScrollToIndex 

pub struct SemanticsScrollToIndex { /* private fields */ }

What a list does when a screen reader asks for the row at an index, e.g. a TalkBack scroll-to-position action.

This is Compose’s SemanticsActions.ScrollToIndex. The index counts rows from zero, and the answer says whether the list moved.
