ExGram.Handler behaviour (ex_gram v0.65.0)

Copy Markdown View Source

Behaviour for handling updates in ExGram.Bot implementations.

Implement this behaviour in your bot module to handle incoming updates from Telegram. The handle/2 callback receives parsed messages and a context struct, while handle_error/1 handles any errors that occur during message processing.

See the Handling Updates guide for more details.
