Struct DeltaEncoder 

pub struct DeltaEncoder;

Delta encoder.

Implementations

impl DeltaEncoder

pub fn new() -> Self

Create a new delta encoder.

pub fn encode(base: &[u8], target: &[u8]) -> Vec<u8>

Encode a delta from base to target.

pub fn encode_with_index( index: &HashMap<[u8; 4], Vec<usize>>, base: &[u8], target: &[u8], ) -> Vec<u8>

Encode a delta using a pre-built index (avoids rebuilding for sliding window).

pub fn estimate_delta_size(base: &[u8], target: &[u8]) -> usize

Estimate the encoded delta size without allocating the output.

pub fn estimate_delta_size_with_index( index: &HashMap<[u8; 4], Vec<usize>>, base: &[u8], target: &[u8], ) -> usize

Estimate delta size using a pre-built index (avoids rebuilding for sliding window).

pub fn build_index(base: &[u8]) -> HashMap<[u8; 4], Vec<usize>>

Build a 4-byte hash index over the base data.

Trait Implementations

impl Debug for DeltaEncoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for DeltaEncoder

fn default() -> Self

Returns the “default value” for a type.
