std::inplace_vector<T,N>::assign_range - cppreference.com

Replaces elements in the container with a copy of each element in rg.

Each iterator in the range rg is dereferenced exactly once.

If rg overlaps with *this, the behavior is undefined.

• std::bad_alloc, if std::ranges::distance(rg) > capacity().
• Any exception thrown by initialization of inserted element.

#include <algorithm>
#include <cassert>
#include <initializer_list>
#include <inplace_vector>
#include <iostream>
#include <new>
 
int main()
{
    const auto source = {1, 2, 3};
    std::inplace_vector<int, 4> destination{4, 5};
    destination.assign_range(source);
    assert(std::ranges::equal(destination, source));
 
    try
    {
        const auto bad = {-1, -2, -3, -4, -5};
        destination.assign_range(bad); // throws: bad.size() > destination.capacity()
    }
    catch(const std::bad_alloc& ex)
    {
        std::cout << ex.what() << '\n';
    }
}
