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

Since C++26

Conditionally appends the given element value to the end of the container.

# Declarations

(since C++26)

# Parameters

value: the value of the element to append

# Return value

std::addressof(back()) if size() < capacity(), nullptr otherwise.

int main()

    std::string dog{"dog"};
 
    std::string* p1 = pets.try_push_back("cat"); // overload (1)
    assert(*p1 == "cat" and pets.size() == 1);
 
    std::string* p2 = pets.try_push_back(std::move(dog)); // overload (2)
    assert(*p2 == "dog" and pets.size() == 2);
 
    assert(pets[0] == "cat" and pets[1] == "dog");
