std::counted_iterator<I>::operator=
template <class I2> requires std::assignable_from<I&, const I2&> constexpr counted_iterator& operator=( const counted_iterator<I2>& other ); |
(since C++20) |
The underlying iterator and length are assigned with those of other.
Parameters
| other | - | iterator adaptor to assign from |
Return value
*this.
Example
#include <algorithm>
#include <cassert>
#include <initializer_list>
#include <iterator>
int main()
{
auto a = {3, 1, 4, 1, 5, 9, 2};
std::counted_iterator<std::initializer_list<int>::iterator> p(begin(a), size(a)-2);
std::counted_iterator<std::initializer_list<int>::iterator> q;
assert(q.count() == 0);
assert(q.count() != p.count());
q = p;
assert(q.count() == p.count());
assert(std::ranges::equal(p, std::default_sentinel, q, std::default_sentinel));
}
