Struct ckb_merkle_mountain_range::MerkleProof

pub struct MerkleProof<T, M> { /* private fields */ }

Implementations

impl<T: PartialEq + Debug + Clone, M: Merge<Item = T>> MerkleProof<T, M>

pub fn new(mmr_size: u64, proof: Vec<T>) -> Self

pub fn mmr_size(&self) -> u64

pub fn proof_items(&self) -> &[T]

pub fn calculate_root(&self, leaves: Vec<(u64, T)>) -> Result<T>

pub fn calculate_root_with_new_leaf(
    &self,
    leaves: Vec<(u64, T)>,
    new_pos: u64,
    new_elem: T,
    new_mmr_size: u64
) -> Result<T>

from merkle proof of leaf n to calculate merkle root of n + 1 leaves. by observe the MMR construction graph we know it is possible. https://github.com/jjyr/merkle-mountain-range#construct this is kinda tricky, but it works, and useful

pub fn verify(&self, root: T, leaves: Vec<(u64, T)>) -> Result<bool>
