Function offset_ptr_by_bytes_mut 

fn offset_ptr_by_bytes_mut<T, U>(ptr: *mut T, offset: isize) -> *mut U

Offset ptr by offset bytes and cast the result to *mut U.

The result must be a correctly aligned pointer to a valid value of type U.

Panics:

This function panics if debug assertions are enabled if adding offset causes ptr to overflow or if the resulting pointer is not correctly aligned.
