Enum parquet2::deserialize::DefLevelsDecoder

pub enum DefLevelsDecoder<'a> {
    Bitmap(HybridDecoderBitmapIter<'a>),
    Levels(HybridRleDecoder<'a>, u32),
}

Decoder of definition levels.

Variants

Bitmap(HybridDecoderBitmapIter<'a>)

When the maximum definition level is 1, the definition levels are RLE-encoded and the bitpacked runs are bitmaps. This variant contains HybridDecoderBitmapIter that decodes the runs, but not the individual values

Levels(HybridRleDecoder<'a>, u32)

When the maximum definition level is larger than 1
