impl<'a, T> Translator<&'a [T]> for SliceDictionaryTranslator<'a, T>

fn translate(&self, value: u32) -> ParquetResult<&'a [T]>

Translate from a decoded value to the output format

fn translate_slice( &self, target: &mut Vec<&'a [T]>, source: &[u32], ) -> ParquetResult<()>

fn translate_chunk( &self, target: &mut Vec<O>, source: &<u32 as Unpackable>::Unpacked, ) -> ParquetResult<()>

Translate from a chunk of unpacked items to the output format and write them to a target.

fn translate_bitpacked_all( &self, target: &mut Vec<O>, decoder: Decoder<'_, u32>, ) -> ParquetResult<()>

Translate and collect all the items in a Decoder to a target.

fn translate_bitpacked_limited<'a>( &self, target: &mut Vec<O>, decoder: Decoder<'a, u32>, limit: usize, ) -> ParquetResult<BufferedBitpacked<'a>>

Translate and collect a limited number of items in a Decoder to a target.

fn translate_bitpacked<'a>( &self, target: &mut Vec<O>, decoder: Decoder<'a, u32>, limit: Option<usize>, ) -> ParquetResult<(usize, Option<HybridRleBuffered<'a>>)>
