 `self.0` stores the bytes of string. Since the string is UTF-8, the first byte is guaranteed to not be 10xxxxx or 11111xxx.
 
 ## Heap Mode
-`self.0` are an encoded pointer to heap, where first byte is 10xxxxxx. 10xxxxxx is chosen because it's a UTF-8 continuation byte and therefore an impossible first byte for inline mode. Since a heap-alignment of 4 is chosen, the pointer's least significant 2 bits are guaranteed to be 0 ([See more](https://doc.rust-lang.org/beta/std/alloc/struct.Layout.html#method.from_size_align)). These bits are swapped with the 10 "tag" bits when de/coding between `self.0` and the address value.

 On the heap, the data starts with a variable length integer encoding of the length, followed by the bytes.
