Struct AnnotId 

pub struct AnnotId {
    pub page: PageIndex,
    pub index: u32,
}

Which annotation: a page and its index in that page’s raw /Annots array.

The index space is the raw array, not a filtered position

This distinction is invisible until a page carries a pop-up annotation, and then it decides whether an appearance lands on the right widget.

A page’s annotation list as the rendering path builds it drops pop-ups, so a widget’s position in that list is not its position in the file’s /Annots array: on a page whose first annotation is a pop-up, every later widget’s filtered position is one lower than its raw index.

The appearance overlay a caller draws through is keyed by the raw index. Hand back a filtered position and every appearance after the first pop-up lands on the wrong annotation, silently, with no type to catch it.

Fields

page: PageIndex

Which page.

index: u32

Which entry of that page’s /Annots array — the raw index, counting pop-ups.
