#changed? | Determines whether a value has changed for dirty checking. |
#changed_in_place? | Determines whether the mutable value has been modified since it was read. |
#deserialize | Converts a value from database input to the appropriate ruby type. |
#eql? | Alias for ActiveModel::Type::Value#==. |
#hash, | |
#serializable? | Returns true if this type can convert |
#serialize | Casts a value from the ruby type to a type that the database knows how to understand. |
#type | Returns the unique type name as a |
#cast_value | Convenience method for types which do not need separate type casting behavior for user and database inputs. |
