mostly the Result type. MustGet where you’d except a panic OrElse to pass a fallback value (can be a function with return value of the same type, as the inner function, but without an error). Useful in e.g. more complex constructors where some fields might not be readily available. Either can for instance be useful to have arbitrary type unions in structs. I haven’t used Option that much but seems similar to Rust’s.
