The crab is public domain, so you can use it to advertise your own Rust project or whatever. The gear logo belongs to the Rust foundation, which sparked some controversy a while ago.

I could be wrong, but based on the Wikipedia article it seems like it’s more trying to be a python replacement than a rust/c++/Java/etc replacement. The big thing with rust is that it’s rules allow memory safety without a garbage collector, while unless I missed something it seems like nim just uses a garbage collector. Not that that’s necessarily some huge problem or anything, but you know, different purposes

Can compile to C which then compiles using your favourite compiler. So it can operate at the speed of C

And the new memory management system is similar to rusts system (and can be fully disabled if you want manual memory management)

I think it transpiles to C so theoretically it could be quite fast, but I doubt the generated C is as fast as manually written C or Rust.
