RangeInclusionEvidence

dig_evidence

Struct RangeInclusionEvidence 

Source 
pub struct RangeInclusionEvidence { /* private fields */ }
Expand description

Authenticated evidence that a range leaf is included under a generation root.

Its fields are PRIVATE and exposed only through accessors: the only way to obtain a value is gather, which folds the supplied path and confirms it reaches the claimed root. A value therefore witnesses that the inclusion genuinely holds.

Implementations§

Source§

impl RangeInclusionEvidence

Source

pub fn generation_root(&self) -> CapsuleBytes32

The generation root the range leaf is proven to be included under.

Source

pub fn leaf(&self) -> CapsuleBytes32

The range’s merkle leaf digest this evidence proves inclusion of.

Source

pub fn path(&self) -> &[ProofStep]

The inclusion path (sibling hashes + sides) folded to reach the root.

Source§

impl Evidence for RangeInclusionEvidence

Source§

fn gather<S: ChainSource>( claim: &Self::Claim, _chain: &S, ) -> EvidenceResult<Self>

Authenticates the supplied inclusion inputs OFFLINE — chain is unused because a range proof is fully self-contained. Builds the MerkleProof from the claim and folds it; a path that does not reach generation_root is rejected with EvidenceError::ProofDoesNotFold.

Source§

fn verify(&self) -> EvidenceResult<()>

Re-folds the stored path offline and confirms it still reaches the stored root.
