Enum lightning::chain::keysinterface::SpendableOutputDescriptor

pub enum SpendableOutputDescriptor {
    StaticOutput {
        outpoint: OutPoint,

    },

When on-chain outputs are created by rust-lightning an event is generated which informs the user thereof. This enum describes the format of the output and provides the OutPoint.

Variants

StaticOutput

Fields

outpoint: OutPoint

The outpoint spendable by user wallet

output: TxOut

The output which is referenced by the given outpoint

Outpoint with an output to a script which was provided via KeysInterface, thus you should have stored somewhere how to spend script_pubkey! Outputs from a justice tx, claim tx or preimage tx

DynamicOutput

Fields

outpoint: OutPoint

Outpoint spendable by user wallet

local_delayedkey: SecretKey

local_delayedkey = delayed_payment_basepoint_secret + SHA256(per_commitment_point || delayed_payment_basepoint

witness_script: Script

witness redeemScript encumbering output

to_self_delay: u16

nSequence input must commit to self_delay to satisfy script’s OP_CSV

Outpoint commits to a P2WSH, should be spend by the following witness : <local_delayedsig> 0 With input nSequence set to_self_delay. Outputs from a HTLC-Success/Timeout tx
