- The panic keyword is similar to the todo keyword, - but it is used to crash the program when the program has reached a point that - should never be reached. -

-

- This keyword should almost never be used! It may be useful in initial - prototypes and scripts, but its use in a library or production application is - a sign that the design could be improved. With well designed types the type - system can typically be used to make these invalid states unrepresentable. -
