Function git_pack::data::output::count::objects_unthreaded

pub fn objects_unthreaded<Find, IterErr, Oid>(
    db: Find,
    object_ids: impl Iterator<Item = Result<Oid, IterErr>>,
    progress: impl Progress,
    should_interrupt: &AtomicBool,
    input_object_expansion: ObjectExpansion
) -> Result<Error<Find::Error>, IterErr> where
    Find: Find,
    Oid: Into<ObjectId>,
    IterErr: Error, 

Like objects() but using a single thread only to mostly save on the otherwise required overhead.
