-// errors2.rs
-//
-// Say we're writing a game where you can buy items with tokens. All items cost
-// 5 tokens, and whenever you purchase items there is a processing fee of 1
-// token. A player of the game will type in how many items they want to buy, and
-// the `total_cost` function will calculate the total cost of the items. Since
-// the player typed in the quantity, though, we get it as a string-- and they
-// might have typed anything, not just numbers!
-//
-// Right now, this function isn't handling the error case at all (and isn't
-// handling the success case properly either). What we want to do is: if we call
-// the `total_cost` function on a string that is not a number, that function
-// will return a `ParseIntError`, and in that case, we want to immediately
-// return that error from our function and not try to multiply and add.
-//
-// There are at least two ways to implement this that are both correct-- but one
-// is a lot shorter!
-//
-// Execute `rustlings hint errors2` or use the `hint` watch subcommand for a
-// hint.
-
-// I AM NOT DONE
