For reference I have over a decade of JavaScript experience in industry and my async Rust rewrite of a large JS project was *more* concise then the heavily refactored and polished NodeJS version (a language I consider more concise then most). If you are having to copy and paste excessively in Rust that is an issue but it is not necessarily intrinsic to the language.
For what it's worth traits largely prevented copy and paste and where traits fail there are macros. The classic inheritance example you link to is a tiny percentage of my code and an orders of magnitude smaller time sink when compared to the code maintenance problems I faced in other languages.
