|
||
<p>This <strong>only works</strong> if the enum uses the default <em>externally tagged</em> representation.
|
||
Other enum representations are not supported.</p>
|
||
<p>serde data formats often represent <em>externally tagged</em> enums as maps with a single key.
|
||
The key is the enum variant name, and the value is the variant value.
|
||
Sometimes a map with multiple keys should be treated like a list of enum values.</p>
