Struct Anchor 

pub struct Anchor<D>
where
    D: Proof,
{
    pub mpc_proof: MerkleProof,
    pub dbc_proof: D,
}

Anchor is a data structure used in deterministic bitcoin commitments for keeping information about the proof of the commitment in connection to the transaction which contains the commitment, and multi-protocol merkle tree as defined by LNPBP-4.

Fields

mpc_proof: MerkleProof

Structured multi-protocol LNPBP-4 data the transaction commits to.

dbc_proof: D

Proof of the DBC commitment.

Implementations

impl<D> Anchor<D>

where D: Proof,

pub fn new(mpc_proof: MerkleProof, dbc_proof: D) -> Anchor<D>

Constructs anchor for a given witness transaction id, MPC and DBC proofs.

impl<D> Anchor<D>

where D: Proof,

pub fn verify( &self, protocol_id: impl Into<ProtocolId>, message: impl Into<Message>, tx: &Transaction, ) -> Result<Commitment, VerifyError<<D as Proof>::Error>>

Verifies that the transaction commits to the anchor and the anchor commits to the given message under the given protocol.

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

Verifies that the anchor commits to the given message under the given protocol.

Trait Implementations

where D: Debug + Proof,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<D> Ord for Anchor<D>

where D: Ord + Proof,

fn cmp(&self, other: &Anchor<D>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

impl<D> PartialEq for Anchor<D>

where D: PartialEq + Proof,

fn eq(&self, other: &Anchor<D>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
