In Case You Don't Know, Rust is The New "C"

Good read: “Rust is the future of systems programming, C is the new Assembly”: Intel principal engineer, Josh Triplett

I really couldn't see this before, but Rust is a replacement for C/C++, a clean replacement.

Redox is a Unix-like Operating System written in Rust, aiming to bring the innovations of Rust to a modern microkernel and full set of applications.

And Wasmer is pretty promising for the web world:

Even it might takeover current big C/C++ implementations like this one:

RustPython

A Python-3 (CPython >= 3.10.0) Interpreter written in Rust 🐍 😱 🤘.

Usage

Check out our online demo running on WebAssembly.

RustPython requires Rust latest stable version (e.g 1.43.0 at May 24th 2020) To check Rust version: rustc --version If you wish to update rustup update stable.

To build RustPython locally, do the following:

$ git clone https://github.com/RustPython/RustPython
$ cd RustPython
  # --release is needed (at least on windows) to prevent stack overflow
$ cargo run --release demo.py
Hello, RustPython

Or use the interactive shell:

$ cargo run --release
Welcome to rustpython
>>>>> 2+2
4

NOTE: For windows users, please set RUSTPYTHONPATH environment variable as Lib path in project directory. (e.g. When RustPython directory is C:\RustPython, set RUSTPYTHONPATH as C:\RustPython\Lib)

You can also install and run RustPython with the following:

$ cargo install --git https://github.com/RustPython/RustPython
$ rustpython
Welcome to the magnificent Rust Python interpreter
