Function croaring_sys::roaring64_iterator_previous
source ยท pub unsafe extern "C" fn roaring64_iterator_previous(
it: *mut roaring64_iterator_t
) -> bool
Expand description
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.
