In the example, Color::unknown is not defined in the mapping used to call <code>NLOHMANN_JSON_SERIALIZE_ENUM_STRICT</code> so causes an exception when used to serialize. Similarly, "what" does not refer to an enum value so also causes an exception when deserialization is attempted.</p> <div class=highlight><pre><span></span><code><span class=cp>#include</span><span class=w> </span><span class=cpf><iostream></span>
