pub fn decode_selected(bytes: &[u8], positions: &[usize]) -> Result<Vec<i64>>Expand description
Decodes selected row positions from a chunk written by encode.
Positions must be sorted and unique. Packed chunks read only the words holding those positions, and run length chunks walk their run boundaries without expanding the output. Other cascade shapes use the full decoder and select afterward until they have a point form of their own.
ยงErrors
As decode, or if a position is outside the chunk or the positions are not strictly
increasing.
