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.

Here is Redox OS:

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:

🚀 The leading WebAssembly Runtime supporting WASI and Emscripten

Wasmer is a fast and secure WebAssembly runtime that enables super lightweight containers to run anywhere: from Desktop to the Cloud, Edge and IoT devices.

This document is also available in 🇨🇳 中 文 -Chinese🇩🇪 Deutsch-German🇪🇸 Español-Spanish🇫🇷 Français-French🇯🇵 日本 語 -Japanese🇰🇷 한국어 -Korean.


  • Secure by default. No file, network, or environment access, unless explicitly enabled.
  • Supports WASI and Emscripten out of the box.
  • Fast. Run WebAssembly at near-native speeds.
  • Embeddable in multiple programming languages
  • Compliant with latest WebAssembly Proposals (SIMD, Reference Types, Threads, ...)


Wasmer CLI ships as a single executable with no dependencies.

curl -sSfL | sh
Enter fullscreen mode Exit fullscreen mode
Other installation options (Powershell, Brew, Cargo, ...)

Wasmer can be installed from various package managers. Choose the one that fits best for your environment:

  • Powershell (Windows)

    iwr -useb | iex
    Enter fullscreen mode Exit fullscreen mode
  • Homebrew (macOS, Linux)

    Enter fullscreen mode Exit fullscreen mode

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

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
$ cd RustPython
  # --release is needed (at least on windows) to prevent stack overflow
$ cargo run --release
Hello, RustPython

Or use the interactive shell:

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

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
$ rustpython
Welcome to the magnificent Rust Python interpreter

What other Rust potential use-cases do you see?

I'd like to see a Rust/Gecko/Quantum/SpiderMonkey implementation of Electron (replacing C++/Chromium).

I'm preatty new to Rust, so the obvious question (for me) is: "why Rust over Golang in these cases"?

Nielvdw • Edited

Golang won't work for these cases. A garbage collector is like a layer on which the rest of the program runs. It's very unstable to bootstrap the GC in an OS kernel BEFORE the kernel runs. Aka you need a kernel first to run a GC, and with Golang you will need the GC first to run the kernel. Similar thing applies to many other systems, the extra GC layer is a continual pain point.

Besides what @nielvandw and @buinauskas have already mentioned.

Before writing the post, I've done some research and found that Rust and Go are not competitors.

And I would also wanna add that Go is very very use-case-specific to Google-like products (scalable solutions made by tech gaints like Digital Ocean or Docker).

AFAIK Rust is faster and is designed to be a systems programming language.

Go, on the other hand, is designed for microservices, web based tasks for high concurrency, easy vertical and horizontal scaling.

no way ! C++ was the new C ! :)

Sorry, it's true.
