match Expression
A Rust expression for exhaustive branching by pattern
Core Idea
match is Rust's pattern-based branching expression. Unlike a loose if chain, it pushes you to handle every relevant case, which lets the compiler catch missing branches as the data model grows.
Why It Matters Here
Mathbong uses match as the hub for enum state branching, Option handling, and Result error flows. It is one of the clearest examples of Rust turning careful thinking into compile-time checks.
