Struct BatchControl 

pub struct BatchControl {
    pub batch_num: u32,
    pub has_more: bool,
    pub status: BatchStatus,
    pub last_seq_id: Option<SeqId>,
}

Batch control metadata for paginated initial data loading.

Fields

batch_num: u32

Current batch number (0-indexed).

has_more: bool

Whether more batches are available to fetch.

status: BatchStatus

Loading status for the subscription.

last_seq_id: Option<SeqId>

The SeqId of the last row in this batch (used for subsequent requests).

Implementations

impl BatchControl

pub fn first(has_more: bool) -> BatchControl

Create a batch control for the first batch (batch_num=0).

pub fn subsequent(batch_num: u32, has_more: bool) -> BatchControl

Create a batch control for a subsequent batch (batch_num > 0).

pub fn new( batch_num: u32, has_more: bool, last_seq_id: Option<SeqId>, ) -> BatchControl

Create batch control with all fields specified.

Trait Implementations

impl Clone for BatchControl

fn clone(&self) -> BatchControl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchControl

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BatchControl

fn deserialize<__D>( __deserializer: __D, ) -> Result<BatchControl, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for BatchControl

impl PartialEq for BatchControl

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for BatchControl

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
