Enum CandidateSource 

pub enum CandidateSource {
    StagedAgainstHead,
    StagedAgainstCommit(ObjectId),
    Committed(ObjectId),
}

What: Which Git state a version lists, and what it is compared with. #[derive(...)] generates cloning, debug printing and ==. Why: A commit being prepared is judged by what is staged; a landed commit by what it changed. Naming the comparison makes the version reproducible.

In TS you’d write (pseudocode):

type CandidateSource = { kind: 'staged-against-head' } | { kind: 'staged-against-commit'; commit: ObjectId } | { kind: 'committed'; commit: ObjectId };

Variants

StagedAgainstHead

The index compared with HEAD; every index entry when no commit exists yet.

StagedAgainstCommit(ObjectId)

The index compared with one named commit, such as a transaction’s recorded base.

Committed(ObjectId)

One commit compared with each of its parents; every entry of a root commit.
