A quick reference of the sigils and their meaning:
| Sigil | Meaning |
| ----- | ------- |
| `~` | Owned pointer; like a normal value, but always pointer-sized, and allocated on the heap |
| `&` | Borrowed pointer; a pointer to data that you do not own and thus cannot free |
| `&mut`| Mutable borrowed pointer; like a borrowed pointer, but cannot alias with any other pointer, and you can mutate through it |
| `@` | Managed pointer; a pointer to data that no one owns. Allows cycles. Garbage collected |
| `'` | Lifetime/label marker; used to label loops for labeled break and to indicate the lifetime of a borrowed pointer (eg `&'a T`) |
| `*` | Raw pointer; just like a pointer in C. Requires unsafe code to dereference. Can be NULL |
