            <title>[SERVER-51888] Add TS2&apos;s std::is_detected etc API to stdx</title>
                <link>https://jira.mongodb.org/browse/SERVER-51888</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;It&apos;s a pre-standard API. This is what stdx is for.&lt;br/&gt;
It would be useful for simplifying decltype-based traits in logv2 and elsewhere.&lt;br/&gt;
I needed it for &lt;tt&gt;ASSERT_THAT&lt;/tt&gt; during Skunkworks, so I might as well bring it into stdx.&lt;/p&gt;

&lt;p&gt;MSVC bug that expression sfinae doesn&apos;t consider access modifiers.&lt;/p&gt;

&lt;p&gt;So a private member function will incorrectly pass a detection idiom check. Then trying to call that function of course fails as usual. So you can&apos;t use is_detected on MSVC to correctly identify whether an object has a callable member function. It might have a private member function that would match the decltype call expression, and is_detected will indicate that it&apos;s callable anyway.  I worked around it here by making a private function in ReplSetConfig public. It was an oversight anyway, but really I just got lucky.&lt;/p&gt;</comment>

&lt;p&gt;    ReplSetConfigBase now needs a public serialize to work around MSVC bug&lt;br/&gt;
