Core Idea

An impl block is Rust syntax for attaching methods or trait implementations to a type. impl TypeName { ... } defines inherent methods, while impl Trait for TypeName { ... } states that the type satisfies a shared interface.

Why It Matters Here

Mathbong uses impl blocks to connect struct methods, generic constraints, and trait implementations into one mental model. It is the core syntax behind "attach behavior to a type" in Rust.
