If our goal is to build Apex, our own programming language in Rust, then we need to learn several layers. Think of it as building a city:

Language Design

Lexer
      ↓
Parser

AST
      ↓
Semantic Analysis

Stage 0: Rust Fundamentals

Rust Fundamentals for Compilers

Before compiler theory, you need enough Rust to build large systems.

Important topics:

Ownership & Borrowing

Because compiler data structures are huge trees.

let x = String::from("Hello");
let y = &x;

You must understand:
