Classes

AsStringable

The AsStringable class is a castable class that implements the Castable interface. This class is used for casting Eloquent model attributes to Stringable objects, which allows for convenient string manipulation. The class contains a static castUsing method that returns an anonymous class implementing the CastsAttributes interface. This anonymous class contains the get and set methods, which are responsible for retrieving and setting the casted attribute value respectively. When getting a value, the get method returns a Stringable object created from the attribute value. When setting a value, the set method converts the value to a string if it is not null. Otherwise, it returns null.
