Struct nats::jetstream::NextRequest

pub struct NextRequest {
    pub batch: usize,
    pub expires: Option<usize>,
    pub no_wait: Option<bool>,
}

for getting next messages for pull based consumers.

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: Option<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.
