panic is just different name for exception though.

  Exceptions can be handled, so in rust an "exception" is a "Result<T,U>". A panic means the program terminates, guaranteed. This allows us to ignore hugely difficult edge cases when interacting with hardware / OSes and still ensure the code meets safety guarantees; if the code isn't executing it cannot invalidate any invariants.
