Struct TrustedClosingTransaction

pub struct TrustedClosingTransaction<'a> { /* private fields */ }

A wrapper on ClosingTransaction indicating that the built bitcoin transaction is trusted.

See trust() and verify() functions on CommitmentTransaction.

This structure implements Deref.

Implementations

impl<'a> TrustedClosingTransaction<'a>

pub fn built_transaction(&self) -> &'a Transaction

The pre-built Bitcoin commitment transaction

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.

Methods from Deref<Target = ClosingTransaction>

pub fn trust(&self) -> TrustedClosingTransaction<'_>

Trust our pre-built transaction.

Applies a wrapper which allows access to the transaction.

This should only be used if you fully trust the builder of this object. It should not be used by an external signer - instead use the verify function.

pub fn verify( &self, funding_outpoint: OutPoint, ) -> Result<TrustedClosingTransaction<'_>, ()>

Verify our pre-built transaction.

Applies a wrapper which allows access to the transaction.

An external validating signer must call this method before signing or using the built transaction.

pub fn to_holder_value_sat(&self) -> u64

The value to be sent to the holder, or zero if the output will be omitted

pub fn to_counterparty_value_sat(&self) -> u64

The value to be sent to the counterparty, or zero if the output will be omitted

pub fn to_holder_script(&self) -> &Script

The destination of the holder’s output

pub fn to_counterparty_script(&self) -> &Script

The destination of the counterparty’s output

Trait Implementations

impl<'a> Deref for TrustedClosingTransaction<'a>

type Target = ClosingTransaction

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
