Struct NatsIngress 

pub struct NatsIngress { /* private fields */ }

Minimal blocking NATS ingress adapter.

This adapter subscribes to one NATS subject and exposes each message payload as one ingress message.

Implementations

impl NatsIngress

pub fn new( name: impl Into<String>, server_url: &str, subject: &str, queue_group: Option<&str>, read_timeout: Duration, max_message_bytes: usize, ) -> Result<Self, AdapterError>

Create a blocking NATS ingress adapter.
