Struct 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_counterparty_commitment<T>( &self, funding_key: &SecretKey, funding_redeemscript: &Script, channel_value_satoshis: u64, secp_ctx: &Secp256k1<T>, ) -> Signature

where T: Signing,

Signs the counterparty’s commitment transaction.

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

where T: Signing, ES: Deref, <ES as Deref>::Target: EntropySource,

Signs the holder commitment transaction because we are about to broadcast it.

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 Debug for BuiltCommitmentTransaction

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

Formats the value using the given formatter.

impl Readable for BuiltCommitmentTransaction

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

where R: Read,

Reads a Self in from the given Read.

impl Writeable for BuiltCommitmentTransaction

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

where W: Writer,

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>.
