Struct lightning::ln::channel_keys::PaymentKey

pub struct PaymentKey(pub PublicKey);

localpubkey is a child key of a payment basepoint, that enables a secure hash-lock for off-chain payments without risk of funds getting stuck or stolen. A payment key is normally shared with a counterparty so that it can generate a commitment transaction’s to_remote ouput, which our node can claim in case the counterparty force closes the channel.

Implementations

impl PaymentKey

pub fn from_basepoint<T: Signing>( secp_ctx: &Secp256k1<T>, basepoint: &PaymentBasepoint, per_commitment_point: &PublicKey ) -> Self

Generate localpubkey using per_commitment_point

pub fn from_secret_key<T: Signing>( secp_ctx: &Secp256k1<T>, sk: &SecretKey ) -> Self

Generate localpubkey from privkey

pub fn to_public_key(&self) -> PublicKey

Get inner Public Key

Trait Implementations

impl Clone for PaymentKey

fn clone(&self) -> PaymentKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PaymentKey

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

Formats the value using the given formatter.

impl PartialEq for PaymentKey

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

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

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

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

impl Readable for PaymentKey

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

Reads a Self in from the given Read.

impl Writeable for PaymentKey

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

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

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.
