error: attribute `format` can only be used on structs or variants.
       enums can have the following attributes: `autogen` or `autogenerate`

error: at least one variant has to be constructable from sscanf.
       To do this, add #[sscanf(format = "...")] to a variant

9 | enum TestNoVariants { }

error: FromScanf: autogen only works if the variants have no fields.
       Use `#[sscanf(format = "...")]` to specify a format for a variant with fields or `#[sscanf(skip)]` to skip a variant

error: invalid value for autogen: "casesensitive". Did you mean "CaseInsensitive"?
