Struct ChunkDelta

Source

pub struct ChunkDelta {
    pub added: Vec<ChunkRef>,
    pub removed: Vec<ChunkRef>,
    pub unchanged: usize,
    pub efficiency: f64,
    pub full_upload_recommended: bool,
}

Expand description

Result of diffing two ordered chunk lists.

Efficiency semantics:

0.0 when new is empty (no chunks = no efficiency to measure).
1.0 when all new chunks already exist in old (perfect dedup).

Fields§

§added: Vec<ChunkRef>

Chunks in new not present in old – must be uploaded.

§removed: Vec<ChunkRef>

Chunks in old not present in new – become orphans (handled by compact()).

§unchanged: usize

Number of chunks shared between old and new (reused, no upload needed).

§efficiency: f64

Fraction of new chunks that are reused: unchanged / new.len(). 1.0 = no change. 0.0 = all new (or empty).

§full_upload_recommended: bool

If true, >80% of old chunks changed – full re-upload is more efficient than delta.
