910909This is how you generally move from ‘crash on error’ to ‘actually handle the
911- error’, by switching from ` expect()` to a ` match` statement. The ` Result`
912- returned by ` parse()` is an ` enum` like ` Ordering` , but in this case, each
913- variant has some data associated with it: ` Ok` is a success, and ` Err` is a
910+ error’, by switching from ` expect()` to a ` match` statement. A ` Result` is

912+ each variant has some data associated with it: ` Ok` is a success, and ` Err` is a
914913failure. Each contains more information: the successfully parsed integer, or an
915- error type. In this case, we ` match` on ` Ok(num)` , which sets the inner value
916- of the ` Ok` to the name ` num` , and then we return it on the right-hand
917- side. In the ` Err` case, we don’t care what kind of error it is, so we
