Message Types

There are several functions used to send outgoing messages through the Mixnet, each with a different level of customisation:

• send(&self, message: InputMessage) -> Result<()> Sends a InputMessage to the mixnet. This is the most low-level sending function, for full customization. Called by send_message().

• send_message<M>(&self, address: Recipient, message: M, surbs: IncludedSurbs) -> Result<()> Sends bytes to the supplied Nym address. There is the option to specify the number of reply-SURBs to include. Called by send_plain_message().

• send_plain_message<M>(&self, address: Recipient, message: M) -> Result<()> Sends data to the supplied Nym address with the default surb behaviour.

Note we specify outgoing messages above: this is because the SDK assumes that replies will be anonymous via SURBs.

Replies rely on the creation of an AnonymousSenderTag by parsing and storing the sender_tag from incoming messages, and using this to reply, instead of the Receipient type used by the functions outlined above:

send_reply<M>(&self, recipient_tag: AnonymousSenderTag, message: M) -> Result<()> will send the reply message to the supplied anonymous recipient.
