Struct IndexProof

#[non_exhaustive]
pub struct IndexProof {
    pub block_proof: BlockProof,
    pub index_proof: MapProof<String, Hash>,
}

Proof of authenticity for a single index within the database.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

block_proof: BlockProof

Proof of authenticity for the block header.

index_proof: MapProof<String, Hash>

Proof of authenticity for the index. Must contain a single key - a full index name in the form $service_name.$name_within_service, e.g., cryptocurrency.wallets. The root hash of the proof must be equal to the state_hash mentioned in block_proof.

Implementations

impl IndexProof

pub fn new(block_proof: BlockProof, index_proof: MapProof<String, Hash>) -> Self

Creates a new IndexProof object.

pub fn verify( &self, validator_keys: &[PublicKey], ) -> Result<(&str, Hash), ProofError>

Verifies this proof, returning the full index name (e.g., cryptocurrency.wallets) and its hash on success.
