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

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.

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)

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.
