Struct RedisPubSubPublisher 

Source 
pub struct RedisPubSubPublisher { /* private fields */ }
Expand description

Publishes Pub/Sub messages with PUBLISH (classic) or SPUBLISH (sharded).

Obtain it from RedisBroker::pubsub_publisher. The publish mode must match how subscribers subscribed: a sharded publish only reaches sharded subscribers. Headers are framed around the payload; set a codec for a readable wire format (it must match the subscriber’s).

Implementations§

Source§

impl RedisPubSubPublisher

Source

pub const fn mode(self, mode: PubSubMode) -> Self

Sets the publish mode. Defaults to whatever RedisBroker::pubsub_publisher selected.

Source

pub fn codec(self, codec: impl Codec + 'static) -> Self

Serializes the header/payload envelope with codec (must match the subscriber). Without it the default lossless binary framing is used.
