Struct Delta 

pub struct Delta {
    pub address: Address,
    pub kind: DeltaKind,
    pub fidelity: Fidelity,
    pub before: Option<String>,
    pub after: Option<String>,
    pub lines: Vec<Line>,
    pub package: Option<PackageId>,
    pub summary: Option<String>,
}

One addressed difference inside a Diff, carried at its own rung.

before and after hold content ids, not content: the identity of the bytes on each side, absent when the side does not exist. lines carries the text-rung comparison and is empty at the binary rung. package names the format package whose projection or differ produced the delta — outputs carry the package version (ADR-0003) — and is None at rungs no package produced: the binary floor and plain-text raises. summary is a rich delta’s difference in the format’s own terms — the affected text and the property change — and None below the rich rung.

Fields

address: Address

Where the delta lands, in the format’s own terms.

kind: DeltaKind

What kind of change the delta records.

fidelity: Fidelity

The rung the delta is carried at.

before: Option<String>

The content id of the before side; None when the side does not exist.

after: Option<String>

The content id of the after side; None when the side does not exist.

lines: Vec<Line>

The text-rung line comparison; empty at the binary rung.

package: Option<PackageId>

The package whose projection or differ produced the delta; None at rungs no package produced.

summary: Option<String>

A rich delta’s difference in the format’s own terms; None below the rich rung.

Implementations

impl Delta

pub fn at_text_rung(self, lines: Vec<Line>, package: Option<PackageId>) -> Delta

This delta raised to the text rung, carrying its line comparison and the package that projected the compared text (None for plain text).

pub fn rich( address: Address, summary: impl Into<String>, package: PackageId, ) -> Delta

A rich-rung delta a format package produced: addressed in the format’s own terms, its difference described by summary.
