/// A type with a customized textual representation. /// /// Types that conform to the `CustomStringConvertible` protocol can provide /// their own representation to be used when converting an instance to a /// string. The `String(describing:)` initializer is the preferred way to /// convert an instance of *any* type to a string. If the passed instance /// conforms to `CustomStringConvertible`, the `String(describing:)` /// initializer and the `print(_:)` function use the instance's custom /// `description` property.
