Converting Rust into WebAssembly via rustc

Rust uses the LLVM compiler, which we’ll create now, in order to generate machine-native code. rustc uses LLVM’s capability to convert the native code into a WebAssembly module. Let’s start converting Rust into a WebAssembly module using rustc.

Getting started with the project

We’ll start with Hello World:

1. Let’s create a file called hello_world.rs:
