Struct DeltaMetadata 

pub struct DeltaMetadata {
    pub base_hash: String,
    pub chain_depth: u32,
    pub original_size: usize,
    pub delta_size: usize,
    pub is_delta: bool,
    pub similarity: f64,
    pub space_savings: f64,
}

Delta encoding metadata

Tracks base references, chain depth, and compression statistics

Fields

base_hash: String

Hash of the base version used for this delta

chain_depth: u32

Chain depth (0 = full version, >0 = delta)

original_size: usize

Original size before delta compression

delta_size: usize

Delta size (or full compressed size if not using delta)

is_delta: bool

Whether this version uses delta encoding

similarity: f64

Similarity score with base (0.0 - 1.0)

space_savings: f64

Space savings percentage

Implementations

impl DeltaMetadata

pub fn full(hash: String, size: usize) -> Self

pub fn delta( base_hash: String, base_chain_depth: u32, original_size: usize, delta_size: usize, similarity: f64, ) -> Self

Create metadata for a delta version

pub fn is_at_max_depth(&self) -> bool

Check if this version is at max chain depth

pub fn compression_ratio(&self) -> f64

Calculate compression ratio
