Struct HashDelaySignClause 

pub struct HashDelaySignClause {
    pub pubkey: PublicKey,
    pub hash: Hash,
    pub block_delta: BlockDelta,
}

A clause that allows to sign and spend the UTXO after a relative timelock, if preimage matching the hash is provided.

Fields

pubkey: PublicKey

hash: Hash

block_delta: BlockDelta

Implementations

impl HashDelaySignClause

pub fn sequence(&self) -> Sequence

Returns the input sequence for this clause.

pub fn extract_preimage_from_witness( witness: &Witness, payment_hash: PaymentHash, ) -> Option<Preimage>

Try to extract the preimage from a witness that spends this clause.

Witness layout: [signature, preimage, tapscript, control_block]. Returns the preimage if it is 32 bytes and hashes to the given payment hash.
