• Option: "None is a totally valid result, usually found in data structures"
  • unwrap(): YOLO use in prototyping
  • expect(...): to indicate the reason you believe None is impossible (or a contract violation for the method)
• Result: 😱 "Errors are unexpected but not bugs; the decision for how to handle them is up to the caller"
  • unwrap(): YOLO "I'm an app and don't know how to handle this error -- I'm fine if the whole process aborts"
  • try! / ?: "Leave the decision about how to handle this error to the caller; they have more information"
  • match / catch: "I'm going to handle the error right here right now"
• panic!: ☠ "The error is a bug and can't be recovered from. Game over man. Rust is allowed to abort the process if it wants"
