    pub outpoint: OutPoint,

    pub output: TxOut,

Information about a spendable output to a P2WSH script.

See SpendableOutputDescriptor::DelayedPaymentOutput for more details on how to spend this.

Fields

outpoint: OutPoint

The outpoint which is spendable.

per_commitment_point: PublicKey

Per commitment point to derive the delayed payment key by key holder.

to_self_delay: u16

The nSequence value which must be set in the spending input to satisfy the OP_CSV in the witness_script.

output: TxOut

The output which is referenced by the given outpoint.

revocation_pubkey: RevocationKey

The revocation point specific to the commitment transaction which was broadcast. Used to derive the witnessScript for this output.

channel_keys_id: [u8; 32]

Arbitrary identification information returned by a call to ChannelSigner::channel_keys_id. This may be useful in re-deriving keys used in the channel to spend the output.

channel_value_satoshis: u64

The value of the channel which this output originated from, possibly indirectly.

channel_transaction_parameters: Option<ChannelTransactionParameters>

The channel public keys and other parameters needed to generate a spending transaction or to provide to a re-derived signer through ChannelSigner::provide_channel_parameters.

Added as optional, but always Some if the descriptor was produced in v0.0.123 or later.

Implementations

impl DelayedPaymentOutputDescriptor

pub const MAX_WITNESS_LENGTH: u64 = 154u64

The maximum length a well-formed witness spending one of these should have. Note: If you have the grind_signatures feature enabled, this will be at least 1 byte shorter.

Trait Implementations

impl Clone for DelayedPaymentOutputDescriptor

fn clone(&self) -> DelayedPaymentOutputDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DelayedPaymentOutputDescriptor

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

Formats the value using the given formatter.

impl Hash for DelayedPaymentOutputDescriptor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DelayedPaymentOutputDescriptor

fn eq(&self, other: &DelayedPaymentOutputDescriptor) -> 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 DelayedPaymentOutputDescriptor

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

Reads a Self in from the given Read.

impl Writeable for DelayedPaymentOutputDescriptor

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<u8>.
