Struct breez_sdk_core::lightning::events::bump_transaction::AnchorDescriptor

pub struct AnchorDescriptor {
    pub channel_derivation_parameters: ChannelDerivationParameters,
    pub outpoint: OutPoint,
}

A descriptor used to sign for a commitment transaction’s anchor output.

Fields

channel_derivation_parameters: ChannelDerivationParameters

The parameters required to derive the signer for the anchor input.

outpoint: OutPoint

The transaction input’s outpoint corresponding to the commitment transaction’s anchor output.

Implementations

impl AnchorDescriptor

pub fn previous_utxo(&self) -> TxOut

Returns the UTXO to be spent by the anchor input, which can be obtained via Self::unsigned_tx_input.

pub fn unsigned_tx_input(&self) -> TxIn

Returns the unsigned transaction input spending the anchor output in the commitment transaction.

pub fn witness_script(&self) -> Script

Returns the witness script of the anchor output in the commitment transaction.

pub fn tx_input_witness(&self, signature: &Signature) -> Witness

Returns the fully signed witness required to spend the anchor output in the commitment transaction.

pub fn derive_channel_signer<S, SP>(&self, signer_provider: &SP) -> S

where S: WriteableEcdsaChannelSigner, SP: Deref, <SP as Deref>::Target: SignerProvider<Signer = S>,

Derives the channel signer required to sign the anchor input.

Trait Implementations

impl Clone for AnchorDescriptor

fn clone(&self) -> AnchorDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnchorDescriptor

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

Formats the value using the given formatter.

impl PartialEq for AnchorDescriptor

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