I’m implementing a unified parameter extractor Params for axum that can handle parameters from Path/Query/Form/Multipart. I have a custom DOM-like type that stores both JSON data and uploaded files:

I’m working on an Axum-based application in Rust, where one of my handlers receives a JSON payload that is deserialized into a MyRequest struct. The struct contains a field my_enum of type MyEnum, which is an enum with variants Foo and Bar.
