When you have 20 routes each being terminated with redundant `res.json(success);\n MiddleWare::Next` I think you can imagine why someone might see it as not lightweight in terms of unnecessary boilerplate - which most Rust webframeworks, async or not, don't require you to write out.
I am mostly naive to Rust and web server frameworks, so its a naive thought that may be completely contraindicated due to other issues, but I don't expect to see meaningless(?)/repetitive code in the advertisement for a framework that advertises as lightweight.
