11461: Extract struct from enum variant filters generics r=jo-goro a=jo-goro Fixes #11452. This PR updates extract_struct_from_enum_variant. Extracting a struct `A` form an enum like ```rust enum X<'a, 'b> { A { a: &'a () }, B { b: &'b () }, } ``` will now be correctly generated as ```rust struct A<'a> { a: &'a () } enum X<'a, 'b> { A(A<'a>), B { b: &'b () }, } ``` instead of the previous ```rust struct A<'a, 'b>{ a: &'a () } // <- should not have 'b enum X<'a, 'b> { A(A<'a, 'b>), B { b: &'b () }, } ``` This also works for generic type parameters and const generics. Bounds are also copied, however I have not yet implemented a filter for unneeded bounds. Extracting `B` from the following enum ```rust enum X<'a, 'b: 'a> { A { a: &'a () }, B { b: &'b () }, } ``` will be generated as ```rust struct B<'b: 'a> { b: &'b () } // <- should be `struct B<'b> { b: &'b () }` enum X<'a, 'b: 'a> { A { a: &'a () }, B(B<'b>), } ``` Extracting bounds with where clauses is also still not implemented.
