TrackingPublishLayer

ruststream_sqlx::outbox

Struct TrackingPublishLayer 

Source 
pub struct TrackingPublishLayer<DB: Database, Records> { /* private fields */ }
Expand description

The publish middleware of an Outbox, from publish_layer.

A message under a registered name is recorded through its record type’s Publish, then sent with OUTBOX_ID_HEADER; a record that fails fails the publish, and the message is not sent. A message under any other name is sent as it is.
