module Line.Messaging.Common.Types

Message types

class Messageable a

A type class representing types to be converted into Message.

It has toType and toObject as its minimal complete definition, but it is not recommended to define any extra instance, as the new type may not work with the LINE APIs.

About existing messageable types, please refer to the following instances. Each instance is matched with a message object described in the LINE documentation.

  Message $ Text "hello",
  Message $ Image "https://example.com/image.jpg" "https://example.com/preview.jpg"
