The Philosopher's Stone
This is a proof-of-concept library
that lets you cast between arbitrary types
in a safe way.
In other words, it's a safe std::mem::transmute
!
Example
let mut string_map: HashMap<u32, String> = HashMap::new();
string_map.insert(42, "world".into());
let bytes_map: HashMap<u32, Vec<u8>> =
ps::hash_map_values(ps::string_bytes()).cast(string_map);
assert_eq!(map[42], b"world");
