-A variable was borrowed as mutable more than once. Erroneous code example:
-
-```
-let mut i = 0;
-let mut x = &mut i;
-let mut a = &mut i;
-// error: cannot borrow `i` as mutable more than once at a time
-```
-
-Please note that in rust, you can either have many immutable references, or one
-mutable reference. Take a look at
-https://doc.rust-lang.org/stable/book/references-and-borrowing.html for more
-information. Example:
-
-
-```
-let mut i = 0;
-let mut x = &mut i; // ok!
-
-// or:
-let mut i = 0;
-let a = &i; // ok!
-let b = &i; // still ok!
-let c = &i; // still ok!
