Struct lightning::ln::chan_utils::BuiltCommitmentTransaction

pub struct BuiltCommitmentTransaction {
    pub transaction: Transaction,
    pub txid: Txid,
}

A pre-built Bitcoin commitment transaction and its txid.

Fields

transaction: Transaction

The commitment transaction

txid: Txid

The txid for the commitment transaction.

This is provided as a performance optimization, instead of calling transaction.txid() multiple times.

Implementations

impl BuiltCommitmentTransaction

pub fn get_sighash_all(
    &self,
    funding_redeemscript: &Script,
    channel_value_satoshis: u64
) -> Message

Get the SIGHASH_ALL sighash value of the transaction.

This can be used to verify a signature.

pub fn sign<T: Signing>(
    &self,
    funding_key: &SecretKey,
    funding_redeemscript: &Script,
    channel_value_satoshis: u64,
    secp_ctx: &Secp256k1<T>
) -> Signature

Sign a transaction, either because we are counter-signing the counterparty’s transaction or because we are about to broadcast a holder transaction.

Trait Implementations

impl Clone for BuiltCommitmentTransaction

fn clone(&self) -> BuiltCommitmentTransaction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Readable for BuiltCommitmentTransaction

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

Reads a Self in from the given Read

impl Writeable for BuiltCommitmentTransaction

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

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

Writes self out to a Vec
