There is no performance penalty for calling C code in Rust. It's as fast as calling C functions from C or Rust functions from Rust. > So, why don't use a simple language but safe like Go?

Can you clarify what you mean? Most data structures and algorithms in the Rust standard library need to be written in Rust because they're generic. It reuses the standard C library when possible and there is no performance penalty for doing so. > Rust is a language more complex to replace to C like "universal language". Go isn't much of a replacement for C. It requires a runtime and includes a global garbage collector. I can't see where Rust falls short as a C replacement though, do you have a reason for claiming this? > Note: I love both languages; Go for web apps and Rust for everything > else (mobile and desktop apps, and servers). Go doesn't target web browsers. Both Rust and Go are perfectly viable for writing servers. I would definitely prefer to write server code in a memory safe language where I don't need to worry about data races, and where I have niceties like type-checked format strings and reusable generic data structures and algorithms provided by the standard library.
