-                            bounds.push(cx.trait_bound(
+        let mut ty_params = params
+            .iter()
+            .filter(|param| matches!(param.kind, ast::GenericParamKind::Type { .. }))


For simplicity, should we directly collect into ty_param_names instead of peeking to see if empty?
r=me either way

Yes, good call. Fixed.
