# mutification Convert immutable reference to mutable reference. When creating a getter and setter as a trait to get a field from a structure in a complex gaming system, this is a crate that safely changes an immutable reference to a mutable reference so that you can bypass the Rust compiler rules where you can't borrow another field at the same time! - `to_mut` crate is more conventient than `to-mut`/`to-mut-proc-macro`. - Support generics. **example** ```rust fn test_to_mut(player: &Player) { player.to_mut().name = "Bruce"; } ```
