Struct DeltaBitPacked 

pub struct DeltaBitPacked { /* private fields */ }

Delta + bit-packed encoding for sorted integers.

Combines delta encoding with bit-packing for optimal compression of sorted integer sequences.

Implementations

impl DeltaBitPacked

pub fn encode(values: &[u64]) -> Self

Encodes sorted values using delta + bit-packing.

pub fn decode(&self) -> Vec<u64>

Decodes back to the original values.

pub fn len(&self) -> usize

Returns the number of values.

pub fn is_empty(&self) -> bool

Returns whether the encoding is empty.

pub fn base(&self) -> u64

Returns the base value.

pub fn bits_per_delta(&self) -> u8

Returns the bits used per delta.

pub fn compression_ratio(&self) -> f64

Returns the compression ratio.

pub fn to_bytes(&self) -> Vec<u8>

Serializes to bytes.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Deserializes from bytes.
