Trait Implementations

impl BatchValueWriter<SimpleUnorderedBatch> for SimpleUnorderedBatchIter

fn is_empty(&self) -> bool

Returns true if there are no more values to write.

fn write_next_value( &mut self, batch: &mut SimpleUnorderedBatch, batch_size: &mut usize, ) -> Result<bool, Error>

Writes the next value (if any) to the batch and updates the batch size accordingly.

fn next_batch_size( &mut self, batch: &SimpleUnorderedBatch, batch_size: usize, ) -> Result<Option<usize>, Error>

Computes the batch size that we would obtain if we wrote the next value (if any) without consuming the value.
