# Memory-Safe-D-Spec

Memory Safety for a program is defined as it being impossible for the program to corrupt memory. Therefore, the Safe D consists only of programming language features that are guaranteed to never result in memory corruption.

Safe D is enabled on a per-module basis by compiling with the -safe compiler switch.

### Proscribed Forms

- Inline assembler.
- Casting away const or immutable attributes.
- Casting away shared attributes.
- Casting from one pointer type to another pointer type, except for:
  - casting to `void*` is allowed
  - casting from a pointer to an arithmetic type to a pointer to another arithmetic type of the same or smaller size is allowed
- Casting from a non-pointer type to a pointer type.

A safe module can import and use the public interface of a system module.

### Limitations

Safe D does not imply that code is portable, uses only sound programming practices, is free of byte order dependencies, or other bugs. It is focussed only on eliminating memory corruption possibilities.
