The authenticated signer for this execution, if there is one.

fn message_id(&mut self) -> Result<Option<MessageId>, ExecutionError>

The current message ID, if there is one.

fn message_is_bouncing(&mut self) -> Result<Option<bool>, ExecutionError>

Consumes some of the execution fuel.

fn send_message( &mut self, message: SendMessageRequest<Vec<u8>>, ) -> Result<(), ExecutionError>

Schedules a message to be sent.

fn subscribe( &mut self, chain: ChainId, name: ChannelName, ) -> Result<(), ExecutionError>
