This is an unfair comparison. For starter this version too is unoptimized, so you need to compare this with the first Rust code, which is about the same size.
Moreover a lot of the "bloat" that comes with Rust code isn't because it's more performant. Neither C++ and Rust try to be faster languages (after all, the optimization tricks you can do with your program is limited to what you can do with Assembly and its cousin, C), they try to be safer by providing more abstractions and restrictions (compile time checks).
