MemoryLane

Struct MemoryLane

pub struct MemoryLane { /* private fields */ }

Expand description

Data-plane lane of a MemorySource: drains pushed payloads for one partition. Polls block (up to the timeout) while the lane is paused or its queue is empty, waking on push and resume.

Trait Implementations§

impl Debug for MemoryLane

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

Formats the value using the given formatter. Read more

impl SourceLane for MemoryLane

type Batch<'a> = MemoryBatch<'a>

The borrowed batch type (a GAT so payloads can borrow lane buffers).

fn id(&self) -> LaneId

This lane’s identity within the current assignment.

fn partition(&self) -> PartitionId

The source partition this lane reads. Used for checkpoint issuing and shard routing fallback.

fn poll( &mut self, max_records: usize, timeout: Duration, ) -> Result<Option<MemoryBatch<'_>>, SourceError>

Poll up to max_records payloads, waiting at most timeout. Ok(None) means nothing arrived — the driver treats it as idle. Implementations must not busy-spin when idle: block up to timeout.
