Struct BatchId 

pub struct BatchId {
    pub partition: PartitionId,
    pub epoch: u32,
    pub seq: u64,
}

Identity of one source poll batch within a partition and assignment epoch. Epochs are bumped on every rebalance so acknowledgements from revoked assignments are recognized as stale and discarded.

Fields

partition: PartitionId

Partition the batch was polled from.

epoch: u32

Assignment epoch the batch belongs to.

seq: u64

Per-partition, per-epoch monotonically increasing sequence number.

Trait Implementations

impl Clone for BatchId

fn clone(&self) -> BatchId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchId

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

Formats the value using the given formatter.

impl Hash for BatchId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BatchId

fn eq(&self, other: &BatchId) -> 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.
