Struct Delta 

pub struct Delta { /* private fields */ }

A delta representing the difference between two byte sequences

Implementations

impl Delta

pub fn new(base_size: usize, target_size: usize) -> Self

Creates a new delta

pub fn add_copy(&mut self, offset: usize, length: usize)

Adds a copy operation

Arguments

• offset - Offset in base data
• length - Number of bytes to copy

pub fn add_insert(&mut self, data: Vec<u8>)

Adds an insert operation

Arguments

• data - Data to insert

pub fn operations(&self) -> &[DeltaOp]

Gets the operations

pub fn base_size(&self) -> usize

Gets the base size

pub fn target_size(&self) -> usize

Gets the target size

pub fn apply(&self, base: &[u8]) -> SyncResult<Vec<u8>>

Applies the delta to base data to produce target data

Arguments

• base - The base data

Returns

The reconstructed target data

pub fn compression_ratio(&self) -> f64

Calculates the compression ratio

Returns

Ratio of delta size to target size (lower is better)
