Deriving JsonSchema with Fields Using Custom Serialization

If you use the #[repr(...)] attribute on an enum to give it a C-like representation, then you may also want to use the serde_repr crate to serialize the enum values as numbers. In this case, you should use the corresponding JsonSchema_repr derive to ensure the schema for your type reflects how serde formats your type.
