<p>Unlike <a href="insert.html" title="cpp/container/map/insert">insert</a> or <a href="emplace.html" title="cpp/container/map/emplace">emplace</a>, these functions do not move from rvalue arguments if the insertion does not happen, which makes it easy to manipulate maps whose values are move-only types, such as <code>std::map<std::string, std::unique_ptr<foo>></code>. In addition, <code>try_emplace</code> treats the key and the arguments to the <code>mapped_type</code> separately, unlike <a href="emplace.html" title="cpp/container/map/emplace">emplace</a>, which requires the arguments to construct a <code>value_type</code> (that is, a <code>std::pair</code>)
