Enum nng::options::protocol::pubsub::Subscribe

pub enum Subscribe {}

Register a topic that the subscriber is interested in.

This option takes an array of bytes, of arbitrary size. Each incoming message is checked against the list of subscribed topics. If the body begins with the entire set of bytes in the topic, then the message is accepted. If no topic matches, then the message is discarded.

To receive all messages, an empty topic (zero length) can be used. To receive any messages, at least one subscription must exist.

Support

• Sockets can set this option when using the Sub v0 protocol.
