> In my experience so far, highly proficient Cpp programmers tend to find rust constraints overly restrictive
For me it's the exact opposite - I find Rust righteously restrictive exactly in places I wish the C++ compiler would complain. For instance, the fact that variables are legal to use after move is an obvious C++ footgun - you almost never want it to actually happen in your code. And then, if one really knows better, Rust has `unsafe`, which I actually never used yet except for providing C/C++ bindings to link a Rust project with Scylla.
So, to sum up, I think that Rust has much better defaults (e.g. move the value by default, everything is const by default, etc.), but still lets you bend the rules explicitly, while in C++ the rules are already slightly bent for you, just in case you need it, which is instead a common source of bugs.
And the adoption of Rust is going great at ScyllaDB. More of it is hopefully coming soon, including a rewrite of user-defined functions support in Rust, which would allow us to fully utilize wasmtime (a very neat Rust project) as the WebAssembly engine.
