IMO one of the biggest downsides to Rust people don’t talk about as much is that there are a lot of abandoned and incomplete crates. The same is of course true in C++ but there is a very mature ecosystem there as others have pointed out. The second thing I’d point out is that while Rust’s build tooling is obviously very nice for some cases, it’s not a silver bullet and C++ build _is_ a solved problem. It just can be a bit more of a lift to get rolling and add new dependencies, but these are infrequent costs. Adding a Rust component to a non-Rust build chain can be very painful, however. Cargo really wants everything to live in Cargo. Last but not least, C++ also has extremely mature and comprehensive static and dynamic analysis tooling. It may be that Rust has begun catching up here, I’m not certain.
