handle to the standard input for your terminal. The next part of the code, .read_line(&mut guess), calls the read_line method on the standard input handle to get input from the user. We’re also passing However, one long line is difficult to read, so it’s best to divide it, two lines for two method calls. Now let’s discuss what this line does. Handling Potential Failure with the Result Type As mentioned expressions next. 65 Functions with Return Values Functions can return values to the code that calls them. We don’t name return values, but we do declare their type after an arrow (->). In Rust, the
