Function roaring64_iterator_previous

pub unsafe extern "C" fn roaring64_iterator_previous(
    it: *mut roaring64_iterator_t,
) -> bool

Decrement the iterator. If there is a new value, then roaring64_iterator_has_value() returns true. Values are traversed in decreasing order. For convenience, returns the result of roaring64_iterator_has_value().

Once this returns false, roaring64_iterator_previous should not be called on the iterator again. Calling roaring64_iterator_advance is allowed.
