class `ActiveModel::Type::String`

Active Model String Type

Attribute type for strings. It is registered under the :string key.

This class is a specialization of ActiveModel::Type::ImmutableString. It performs coercion in the same way, and can be configured in the same way. However, it accounts for mutable strings, so dirty tracking can properly check if a string has changed.
