std::inplace_vector<T,N>::clear

Since C++26

Erases all elements from the container. After this call, size() returns zero.

# Declarations

constexpr void clear() noexcept;

(since C++26)

# Return value

(none)

# Example

#include <iostream>
#include <string_view>
#include <inplace_vector>
 
void print_info(std::string_view rem, const std::inplace_vector<int, 3>& v)
{
    std::cout << rem << "{ ";
    for (const auto& value : v)
        std::cout << value << ' ';
    std::cout << "}\n";
    std::cout << "Size=" << v.size() << '\n';
}
 
int main()
{
    std::inplace_vector<int, 3> container{1, 2, 3};
    print_info("Before clear: ", container);
    container.clear();
    print_info("After clear: ", container);
}
