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

fn test_to_mut(player: &Player) {
    player.to_mut().name = "Bruce";
}
