| Ruby/Rails | Rust |
|-----------|------|
| nil → NoMethodError at runtime | Option<T> → compile-time null safety |
| raise "oops" / rescue | Result<T, E> / ? operator |
| include Enumerable | impl Iterator for MyType |
| Duck typing | Trait bounds: fn foo(x: impl Display) |
| Gemfile / bundle | Cargo.toml / cargo (better tooling) |
| attr_accessor :name | pub name: String (no magic, explicit) |
| case x when ... | match x { ... } (exhaustive, compiler-checked) |
| GC handles everything | You handle everything (ownership, borrowing, lifetimes) |
