🎭 Result §

Dealing with results §

• match result
• ?
  • success → unwrap()
  • error → returns err up the call chain (e.g. returns function)
    • only works if enclosing function has Result return type
• result.is_ok(), result.is_error() → bool
• result.ok() → Option<T> (discards error)
• result.err() → Option<E> (discards result)
