Implementations

impl MerkleProof

pub fn method(&self) -> Method

Method returning copy of MerkleProof::method field. Method used to construct MPC proof (hash function, merklization).

pub fn pos(&self) -> u32

Method returning copy of MerkleProof::pos field. Position of the leaf in the tree.

pub fn cofactor(&self) -> u16

Method returning copy of MerkleProof::cofactor field. Cofactor used by the Merkle tree.

impl MerkleProof

pub fn depth(&self) -> u5

Computes the depth of the merkle tree.

pub fn width_limit(&self) -> u32

Computes the maximum width of the merkle tree.

pub fn factored_width(&self) -> u32

Computes the factored width of the merkle tree according to the formula 2 ^ depth - cofactor.

pub fn into_path(self) -> Confined<Vec<MerkleHash>, 0, 32>

Converts the proof into inner merkle path representation

pub fn to_path(&self) -> Confined<Vec<MerkleHash>, 0, 32>

Constructs the proof into inner merkle path representation

pub fn as_path(&self) -> &[MerkleHash]

Returns inner merkle path representation

pub fn merkle_root(&self) -> Option<MerkleHash>

Returns the root of the merkle path.

If the MPC proof contains only a single message returns None

pub fn convolve( &self, protocol_id: ProtocolId, message: Message, ) -> Result<Commitment, InvalidProof>

Convolves the proof with the message under the given protocol_id, producing Commitment.
