Enum DiffTarget 

#[non_exhaustive]
pub enum DiffTarget {
    WorktreeVsHead,
    WorktreeVsTree(ObjectId),
    IndexVsHead,
    WorktreeVsIndex,
    Commit(ObjectId),
    Trees {
        old: Option<ObjectId>,

What to compare when producing a structured file diff list.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WorktreeVsHead

Working tree and index together vs HEAD’s tree (default uncommitted diff).

WorktreeVsTree(ObjectId)

Working tree (and index) vs a specific tree OID.

IndexVsHead

Index vs HEAD’s tree (--staged).

WorktreeVsIndex

Working tree vs index (--unstaged).

Commit(ObjectId)

Patch introduced by one commit (parent tree vs commit tree).

Trees

Tree diff between two commits (old may be absent for root commits).

Fields

old: Option<ObjectId>

Older commit (left side of the range).

new: ObjectId

Newer commit (right side).
