Struct ChannelPublicKeys

pub struct ChannelPublicKeys {
    pub funding_pubkey: PublicKey,
    pub revocation_basepoint: RevocationBasepoint,
    pub payment_point: PublicKey,
    pub delayed_payment_basepoint: DelayedPaymentBasepoint,
    pub htlc_basepoint: HtlcBasepoint,
}

One counterparty’s public keys which do not change over the life of a channel.

Fields

funding_pubkey: PublicKey

The public key which is used to sign all commitment transactions, as it appears in the on-chain channel lock-in 2-of-2 multisig output.

revocation_basepoint: RevocationBasepoint

The base point which is used (with RevocationKey::from_basepoint) to derive per-commitment revocation keys. This is combined with the per-commitment-secret generated by the counterparty to create a secret which the counterparty can reveal to revoke previous states.

payment_point: PublicKey

The public key on which the non-broadcaster (ie the countersignatory) receives an immediately spendable primary channel balance on the broadcaster’s commitment transaction. This key is static across every commitment transaction.

delayed_payment_basepoint: DelayedPaymentBasepoint

The base point which is used (with derive_public_key) to derive a per-commitment payment public key which receives non-HTLC-encumbered funds which are only available for spending after some delay (or can be claimed via the revocation path).

htlc_basepoint: HtlcBasepoint

The base point which is used (with derive_public_key) to derive a per-commitment public key which is used to encumber HTLC-in-flight outputs.

Trait Implementations

impl Clone for ChannelPublicKeys

fn clone(&self) -> ChannelPublicKeys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelPublicKeys

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

Formats the value using the given formatter.

impl Hash for ChannelPublicKeys

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChannelPublicKeys

fn eq(&self, other: &ChannelPublicKeys) -> 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.

impl Readable for ChannelPublicKeys

fn read<R: Read>(reader: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read.

impl Writeable for ChannelPublicKeys

fn write<W: Writer>(&self, writer: &mut W) -> Result<(), Error>

Writes self out to the given Writer.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.
