-Fat pointers are pointers referencing \"Dynamically Sized Types\" (also
-called DST). DST don't have a statically known size, therefore they can
-only exist behind some kind of pointers that contain additional
-information. Slices and trait objects are DSTs. In the case of slices,
-the additional information the fat pointer holds is their size.
-
-To fix this error, don't try to cast directly between thin and fat
-pointers.
