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:

2. Start writing the Rust code:

We have defined a main function. Similar to C, main is a special function that marks the entry point to a program after it has been compiled as an executable. fn ...
