Struct lnpbp::bp::dbc::pubkey::PubkeyContainer

pub struct PubkeyContainer {
    pub pubkey: PublicKey,
    pub tag: Hash,
    pub tweaking_factor: Option<Hmac<Hash>>,
}

Container for LNPBP-1 commitments. In order to be constructed, commitment requires an original public key and a protocol-specific tag, which must be hashed during commitment process. Here we use pre-hashed version of the tag in order to maximize performance for multiple commitments.

Fields

pubkey: PublicKey

The original public key: host for commitment

tag: Hash

Single SHA256 hash of the protocol-specific tag

tweaking_factor: Option<Hmac<Hash>>

Tweaking factor stored after [PubkeyContainer::commit_verify()] procedure

Trait Implementations

impl Clone for PubkeyContainer

fn clone(&self) -> PubkeyContainer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Container for PubkeyContainer

type Supplement = Hash

Out supplement is a protocol-specific tag in its hashed form

type Host = Option<()>

Our proof contains the host, so we don't need host here

fn reconstruct(
    proof: &Proof,
    supplement: &Self::Supplement,
    _: &Self::Host
) -> Result<Self, Error>

fn deconstruct(self) -> (Proof, Self::Supplement)

fn to_proof(&self) -> Proof

fn into_proof(self) -> Proof

impl Debug for PubkeyContainer

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

Formats the value using the given formatter.

impl Display for PubkeyContainer

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

Formats the value using the given formatter.

impl Eq for PubkeyContainer

impl Hash for PubkeyContainer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<PubkeyContainer> for PubkeyContainer

fn eq(&self, other: &PubkeyContainer) -> bool

This method tests for self and other values to be equal, and is used by ==.
