Implementations

impl MerkleCheckPoint

pub fn new(
    nodes_added: Vec<Hash>,
    nodes_deleted: Bitmap,
    prev_accumulated_nodes_added_count: u32
) -> MerkleCheckPoint

pub fn apply<D, B2>(
    &self,
    mmr: &mut MutableMmr<D, B2>
) -> Result<(), MerkleMountainRangeError> where
    D: Digest,
    B2: ArrayLike<Value = Hash>, 

Apply this checkpoint to the MMR provided. Take care: The deleted set is not compressed after returning from here.

pub fn reset(&mut self)

Resets the current MerkleCheckpoint. The accumulated_nodes_added_count is set to the current MerkleCheckpoints count.

pub fn reset_to(&mut self, checkpoint: &Self)

Resets the current MerkleCheckpoint. The accumulated_nodes_added_count is set to the given MerkleCheckpoints count.

pub fn push_addition(&mut self, hash: Hash)

Add a hash to the set of nodes added.

pub fn push_deletion(&mut self, leaf_index: u32)

Add a a deleted index to the set of deleted nodes.

pub fn nodes_added(&self) -> &Vec<Hash>

Return a reference to the hashes of the nodes added in the checkpoint

pub fn nodes_deleted(&self) -> &Bitmap

Return a reference to the roaring bitmap of nodes that were deleted in this checkpoint

pub fn accumulated_nodes_added_count(&self) -> u32

Return the the total accumulated added node count including this checkpoint

pub fn append(&mut self, mut cp: MerkleCheckPoint)

Merge the provided Merkle checkpoint into the current checkpoint.

pub fn into_parts(self) -> (Vec<Hash>, Bitmap)

Break a checkpoint up into its constituent parts
