Struct async_nats::jetstream::consumer::pull::BatchConfig

pub struct BatchConfig {
    pub batch: usize,
    pub expires: Option<usize>,
    pub no_wait: bool,
    pub max_bytes: usize,
    pub idle_heartbeat: Duration,
}

Used for next Pull Request for Pull Consumer

Fields

batch: usize

The number of messages that are being requested to be delivered.

expires: Option<usize>

The optional number of nanoseconds that the server will store this next request for before forgetting about the pending batch size.

no_wait: bool

This optionally causes the server not to store this pending request at all, but when there are no messages to deliver will send a nil bytes message with a Status header of 404, this way you can know when you reached the end of the stream for example. A 409 is returned if the Consumer has reached MaxAckPending limits.

max_bytes: usize

Sets max number of bytes in total in given batch size. This works together with batch. Whichever value is reached first, batch will complete.

idle_heartbeat: Duration

Setting this other than zero will cause the server to send 100 Idle Hearbeat status to the client
