Required Methods

fn schedule_next( &mut self, context: &mut SchedulerContext, ) -> Result<Vec<ScheduledScanLine>>

Schedule the next batch of data

Normally this equates to scheduling the next page of data into one task. Very large pages might be split into multiple scan lines. Each scan line has one or more rows.

If a scheduler ends early it may return an empty vector.
