class Tapioca::Compilers::Dsl::ActionMailer

`Tapioca::Compilers::Dsl::ActionMailer` generates RBI files for subclasses of [`ActionMailer::Base`](api.rubyonrails.org/classes/ActionMailer/Base.html).

For example, with the following `ActionMailer` subclass:

~~~rb class NotifierMailer < ActionMailer::Base

def notify_customer(customer_id)
  # ...
end

end ~~~

this generator will produce the RBI file `notifier_mailer.rbi` with the following content:

~~~rbi # notifier_mailer.rbi # typed: true class NotifierMailer

sig { params(customer_id: T.untyped).returns(::ActionMailer::MessageDelivery) }
def self.notify_customer(customer_id); end

end ~~~
