}

Expand description

Represents states of CrossJoinStream

Variants§

§

WaitBuildSide

§

FetchProbeBatch

§

BuildBatches(RecordBatch)

Holds the currently processed right side batch

Implementations§

Source §

impl CrossJoinStreamState

Source

fn try_as_record_batch(&mut self) -> Result<&RecordBatch>
