Struct bitpacking::BitPacker1x [−][src]
pub struct BitPacker1x;
BitPacker1x
is standard bitpacking : the integer representation over
b
bits are simply concatenated one after the other.
One block must contain 32 integers
.

fn decompress_sorted(
&self,
initial: u32,
compressed: &[u8],
decompressed: &mut [u32],
num_bits: u8
