) -> bool
Expand description
Decrement the iterator. If there’s a new value, then it->has_value
is true.
The new value is in it->current_value
. Values are traversed in decreasing
order. For convenience, returns it->has_value
.
Once it->has_value
is false, roaring_uint32_iterator_previous
should not
be called on the iterator again. Calling roaring_uint32_iterator_advance
is
allowed.
