Struct StructuralDiffCursor 

pub struct StructuralDiffCursor {
    pub base_root: Option<Cid>,
    pub other_root: Option<Cid>,
    pub markers: Vec<StructuralDiffMarker>,
    pub pending: Vec<Diff>,
}

Stable checkpoint token for structural diff traversal.

The cursor records the tree roots it belongs to, the unvisited structural frontier, and any already-expanded diff entries that have not been emitted yet. Reusing it with different roots returns an error.

Fields

base_root: Option<Cid>

Base tree root CID for cursor validation.

other_root: Option<Cid>

Other tree root CID for cursor validation.

markers: Vec<StructuralDiffMarker>

Remaining structural frames in iterator stack order.

pending: Vec<Diff>

Already-expanded diffs that still need to be emitted.

Implementations

impl StructuralDiffCursor

pub fn start(base: &Tree, other: &Tree) -> Self

pub fn is_empty(&self) -> bool

Return whether this cursor has no more work to resume.
