General NATS connection configuration.

Fields

url: String

Comma-separated list of NATS server URLs (e.g., “nats://localhost:4222,nats://localhost:4223”).

subject: Option<String>

The NATS subject to publish to or subscribe to.

stream: Option<String>

(Consumer only). The JetStream stream name. Required for Consumers.

username: Option<String>

Optional username for authentication.

password: Option<String>

Optional password for authentication.

tls: TlsConfig

TLS configuration.

token: Option<String>

Optional token for authentication.

request_reply: bool

(Publisher only) If true, the publisher uses the request-reply pattern. It sends a request and waits for a response (using core_client.request_with_headers()). Defaults to false.

request_timeout_ms: Option<u64>

(Publisher only) Timeout for request-reply operations in milliseconds. Defaults to 30000ms.

delayed_ack: bool

(Publisher only) If true, do not wait for an acknowledgement when sending to broker. Defaults to false.

no_jetstream: bool

If no_jetstream: true, use Core NATS (fire-and-forget) instead of JetStream. Defaults to false.

subscriber_mode: bool

(Consumer only) If true, use ephemeral Subscriber mode. Defaults to false (durable consumer).

stream_max_messages: Option<i64>

(Publisher only) Maximum number of messages in the stream (if created by the bridge). Defaults to 1,000,000.

deliver_policy: Option<NatsDeliverPolicy>

(Consumer only) The delivery policy for the consumer. Defaults to “all”.

stream_max_bytes: Option<i64>

(Publisher only) Maximum total bytes in the stream (if created by the bridge). Defaults to 1GB.

prefetch_count: Option<usize>

(Consumer only) Number of messages to prefetch from the consumer. Defaults to 10000.
