                <link>https://jira.mongodb.org/browse/SERVER-49770</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Copy without assign&lt;/p&gt;

&lt;p&gt; This class has a user-defined copy constructor but no user-defined assignment operator. If the copy constructor is necessary to manage owned resources then a corresponding assignment operator is usually required. If an object of this type is assigned memory leaks and/or use-after-free errors may occur. Note that a compiler-generated assignment operator will perform only a bit-wise copy for any fields that do not have their own assignment operators defined. Class has user-written copy constructor but no user-written assignment operator&lt;br/&gt;

&lt;p&gt;Not worth to add at this point as the code does not need them.&lt;br/&gt;
