So stick with C++? Changing language is not always the right choice. But it is
a very context dependent decision.

In the classic terminology, Rust is object based not object oriented. The
question is whether inheritance is crucial for the application. Clearly
inheritance is crucial to GTK, so the gtk-rs folk have created an inheritance
system in Rust.
In my experience, unless you are writing a library type, if your code has
lifetime variables then "you are doing it wrong". As soon as I stopped trying
to use any lifetime variables in my Rust applications it all got a lot easier.
Of course for library code that has to worry about lifetimes, they are needed.

Actually the Go core team are very serious about not having generics in Go.
Despite the plethora of proposals, none have really made it. I do wonder if
often the objections to a proposal are more along the lines of "we didn't
think of that so it is not going in".
I think there will eventually be generics in Go, but I have no idea when. To
be open, I have stopped using Go. Not so much because of the language, but
because the GTK and GStreamer bindings are somewhat second rate.

Or use Rust. ;-)

I can't say I will be tempted back to C++, the GTK and GStreamer bindings are
a bit second rate. Having got into D and Rust for doing my desktop
applications, I am not going back.
