Almost every Rust Programming tutorial skips past how Hello World actually works underneath the hood. Those 3 lines of Hello World are very beautiful in Rust, but there is a lot going on behind the scenes to make it so pretty.
In this tutorial, we’ll peel back the layers and look underneath the hood.
We’ll look at the RustLang Compilation and Linking process.
We’ll manually build and link our Rust Language program.
We’ll look at the main function as our global entry function
We”ll change our main function, and use a different global entry function
We’ll ditch standard lib from the build
And we’ll compare our Rust program to the C equivalent and look at all of the cool things Rust has done to make it a nicer experience.
