* [classref boost::container::stored_size stored_size]: the type that will be used to store size-related
parameters inside of the vector. Sometimes, when the static to be used is much less than `std::size_t`
it's interesting to use a smaller unsigned integer types to represent `size()` inside `static_vector``,
so that the size of an empty vector is minimized and cache
performance might be improved. See [classref boost::container::stored_size stored_size] for more details.
See the following example to see how [classref boost::container::static_vector_options static_vector_options] can be
