WebbRust has a number of different smart pointer types in its standard library, but there are two types that are extra-special. Much of Rust’s safety comes from compile-time checks, but raw pointers don’t have such guarantees, and are unsafe to use. *const T and *mut T are called ‘raw pointers’ in Rust.
