How to retrieve an EnumDiscriminant variant from a MyEnum variant?

[seanpianka]

The typenames I'm referencing are from the docs' examples for the trait. I have a MyEnum that derives the discriminant traits, and I would like to convert an instance of a MyEnum variant into the corresponding variant of EnumDiscriminants enum.

Once I achieve that, I'd like to then convert that into a &str. My plan is to convert a given MyEnum into its discriminant name as a string, and include that as a field in a tracing span field:

    #[tracing::instrument(
        err,
        skip(self, command),
        fields(command = %command.as_ref::<&str>())
    )]

where command is an instance of MyEnum.

Is this possible?
