Method try_decode

parquet/src/arrow/push_decoder/mod.rs:418–423

Attempt to decode the next batch of data, or return what data is needed The the decoder communicates the next state with a [`DecodeResult`] See full example in [`ParquetPushDecoderBuilder`] ```no_run # use parquet::arrow::push_decoder::ParquetPushDecoder; use parquet::DecodeResult; # fn get_decoder() -> ParquetPushDecoder { unimplemented!() } # fn push_data(decoder: &mut ParquetPushDecoder, ran

(&mut self)

    /// }
    ///```
    pub fn try_decode(&mut self) -> Result<DecodeResult<RecordBatch>, ParquetError> {
        let current_state = std::mem::replace(&mut self.state, ParquetDecoderState::Finished);
        let (new_state, decode_result) = current_state.try_next_batch()?;
        self.state = new_state;
        Ok(decode_result)
    }

    /// Return a [`ParquetRecordBatchReader`] that reads the next set of rows, or
    /// return what data is needed to produce it.
