Struct ProofStore 

Source 
pub struct ProofStore<D> { /* private fields */ }
Expand description

A store derived from a Proof that can be used to generate proofs over any sub-range of the original range.

Implementations§

Source§

impl<D: Digest> ProofStore<D>

Source

pub fn new<I, H, E>( hasher: &mut H, proof: &Proof<D>, elements: &[E], start_element_pos: u64, root: &D, ) -> Result<Self, Error>
where I: CHasher<Digest = D>, H: Hasher<I>, E: AsRef<[u8]>,

Create a new ProofStore from a valid Proof over the given range of elements. The resulting store can be used to generate proofs over any sub-range of the original range. Returns an error if the proof is invalid or could not be verified against the given root.

Source

pub fn new_from_digests(size: u64, digests: Vec<(u64, D)>) -> Self

Create a new ProofStore from the result of calling Proof::verify_range_inclusion_and_extract_digests. The resulting store can be used to generate proofs over any sub-range of the original range.
