The struct or enum has a generic parameter that does not appear in any field. Rust requires all generic parameters to be used. Unused parameters create ambiguity in type inference.

Remove the unused parameter. Use PhantomData to indicate the type is logically used without storing it. Add a field that uses the generic parameter.
