pub fn pointed(bytes: &[u8]) -> boolExpand description
Whether decode_selected reads a few rows of this chunk for less than decoding all of it.
True for the kinds whose rows can be found without the rows before them: a constant, packed units, and strides or dictionary codes over packed units. A run length chunk walks every run to find where a row is, and a delta chunk adds up every delta before it, so for those a caller that wants a few rows does better decoding the chunk the usual way and picking them out.
