https://svn.boost.org/trac10/ticket/11957 <p> According to the documenetation, both static_vector capacity() and max_size() shall return the static_vector capacity: </p> <pre class="wiki">static_vector public static functions static size_type capacity() noexcept; Returns container's capacity. Throws. Nothing. Complexity. Constant O(1). static size_type max_size() noexcept; Returns container's capacity. Throws. Nothing. Complexity.
