Constant Summary

TYPE_STR =

ZMQ::Socket::Pub

A socket of type ZMQ::Socket::Pub is used by a publisher to distribute data. Messages sent are distributed in a fan out fashion to all connected peers. The ZMQ::Socket#recv function is not implemented for this socket type.

When a ZMQ::Socket::Pub socket enters an exceptional state due to having reached the high water mark for a subscriber, then any messages that would be sent to the subscriber in question shall instead be dropped until the exceptional state ends. The ZMQ::Socket#send function shall never block for this socket type.
