Expand description

Store-independent verification result for a DiffPageProof.

Fields§

§valid: bool

True when both range proofs are valid, bounds match, optional lookahead proofs are valid, and the recomputed diff count matches the page limit.

§base_valid: bool

Whether the base range-page proof verified.

§other_valid: bool

Whether the other range-page proof verified.

§lookahead_valid: bool

Whether the lookahead proofs were absent for a final page or valid for a continued page.

§base_root: Option<Cid>

Base tree root from the proof.

§other_root: Option<Cid>

Other tree root from the proof.

§after: Option<Vec<u8>>

Exclusive cursor lower bound.

§requested_end: Option<Vec<u8>>

Original exclusive upper bound requested by the caller.

§proof_end: Option<Vec<u8>>

Exclusive upper bound covered by the range proofs. For continued pages this is the first omitted diff key; for final pages it equals requested_end.

§limit: usize

Original page limit requested by the caller.

§diffs: Vec<Diff>

Diffs recomputed from verified base/other entries.

§next_cursor: Option<RangeCursor>

Continuation cursor derived from the recomputed page and lookahead.
