std::transform equivalent that makes the code a bit shorter

std::vector numbers { 1, 2, 3 };
 
{
    std::vector<qx::string> strings;
    strings.resize(numbers.size());
    std::transform(
        numbers.begin(),
        numbers.end(),
        strings.begin(),
        [](int nNumber)
        {
            return qx::string::static_from(nNumber);
        });
    return strings;
}

    return qx::transform_return<std::vector>(
        numbers,

        {
            return qx::string::static_from(nNumber);
        });
}

Template Parameters

result_container_t	- any container type, that supports iteration and .insert(it, value)
input_container_t	- any container type, that supports iteration
transform_callable_t	- callable type, that takes input_container_t's element type, the return value of this callable forms result_container_t's element type
result_container_rest_t	- any types required for result_container_t after element type

Parameters

input	- input container, may be moved
transformCallable	- transformation callable

Return values

-	container with transformed elements
