Struct nats::jetstream::BatchOptions

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

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.

Trait Implementations

impl Clone for BatchOptions

fn clone(&self) -> BatchOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BatchOptions

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

Formats the value using the given formatter.

impl Default for BatchOptions

fn default() -> BatchOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BatchOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<usize> for BatchOptions

fn from(batch: usize) -> Self

Converts to this type from the input type.

impl PartialEq for BatchOptions

fn eq(&self, other: &BatchOptions) -> 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 BatchOptions

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
