Trait Implementations

impl FieldEncoder for BinaryFieldEncoder

fn maybe_encode(&mut self, array: ArrayRef) -> Result<Vec<EncodeTask>>

Buffer the data and, if there is enough data in the buffer to form a page, return an encoding task to encode the data.

fn flush(&mut self) -> Result<Vec<EncodeTask>>

Flush any remaining data from the buffers into encoding tasks

fn num_columns(&self) -> u32

The number of output columns this encoding will create

fn finish(&mut self) -> BoxFuture<'_, Result<Vec<EncodedBuffer>>>

Finish encoding and return column metadata buffers
