Struct InlineBitpacking 

pub struct InlineBitpacking { /* private fields */ }

Implementations

impl InlineBitpacking

pub fn new(uncompressed_bit_width: u64) -> Self

pub fn from_description(description: &InlineBitpacking) -> Self

pub fn min_size_bytes(compressed_bit_width: u64) -> u64

The minimum number of bytes required to actually get compression

We have to compress in blocks of 1024 values. For example, we can compress 500 2-byte (1000 bytes) values into 1024 2-bit values (256 bytes) for a win but we don’t want to compress 10 2-byte values into 1024 2-bit values because that’s not a win.
