std::flat_multiset<Key,Compare,KeyContainer>::replace

Since C++23

Replaces the underlying container c. Equivalent to: c = std::move(cont);.

# Declarations

void replace( container_type&& cont );

(since C++23)

# Parameters

cont: a sorted container of type KeyContainer, the contents of which will be moved into *this

# Return value

(none)

# Example

#include <algorithm>
#include <cassert>
#include <flat_set>
#include <print>
#include <vector>
 
int main()
{
    std::vector<int> keys{1, 2, 3};
    assert(std::ranges::is_sorted(keys));
 
    std::flat_multiset<int> set;
    assert(set.empty());
 
    set.replace(keys);
    assert(set.size() == 3);
    assert(keys.empty());
 
    std::println("{}", set); // set.keys()
}
