Enum ApMode 

pub enum ApMode {
    Normal,
    Rollover,
    Down,
}

Which appearance a lookup wants.

use pdfrum_doc::annot::{ApMode, annot_ap, has_appearance};
use pdfrum_object::{ByteSpan, Dict, Name, NoResolve, Object, Stream};

let normal = Stream::new(Dict::default(), ByteSpan::whole(b"0 0 10 10 re f".as_slice().into()));
let annot = Dict::from_pairs([(
    Name::from("AP"),
    Object::Dict(Dict::from_pairs([(
        Name::from("N"),
        Object::Stream(Box::new(normal)),
    )])),
)]);

// A missing `/R` falls back to `/N` when the caller allows it.
assert!(annot_ap(&annot, ApMode::Rollover, true, &NoResolve).is_some());
assert!(annot_ap(&annot, ApMode::Rollover, false, &NoResolve).is_none());
