Ehh you shouldn't need to

Why not use an index instead of counting characters? Or return the index of the failure?

Using '&str' could be useful for easier comparisons too

or even if you have some real complex parsing logic , using a state structure could be useful. Could even create a struct to encapsulate the parser state, including the current index and other info
