/// Type used to construct void pointers for use with C. |

|
/// return type for FFI functions which have the `void` return type in |
|
/// C. Use the unit type `()` or omit the return type instead. |

// functions like malloc(), we need to have it represented as i8* in |

// LLVM bitcode. The enum used here ensures this and prevents misuse |
|
// of the "raw" type by only having private variants.. We need two |
