[Rust 1.3]

I implemented it, tested with the first 2 cases and it worked.
I pasted it to check all sample tests, but it outputs:

error[E0425]: cannot find function `boolfuck` in this scope
  --> src/lib.rs:65:20
   |
65 |         assert_eq!

And below.

   |                    ^^^^^^^^ not found in this scope
help: possible candidate is found in another module, you can import it into scope
   |
1  | use boolfuck;
   |

My function's header is:

fn boolfuck(code: &str, input: Vec<u8>) -> Vec<u8>

I tried using the boolfuck module, but it errored, or I don't know how to use it.
