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

pub struct BatchConfig {
    pub batch: usize,
    pub expires: Option<Duration>,
    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<Duration>

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 Heartbeat status to the client

Trait Implementations

impl Clone for BatchConfig

fn clone(&self) -> BatchConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BatchConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BatchConfig

fn default() -> BatchConfig

Returns the “default value” for a type.

impl PartialEq<BatchConfig> for BatchConfig

fn eq(&self, other: &BatchConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BatchConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
