Struct PsbtInputSatisfier

pub struct PsbtInputSatisfier<'psbt> {
    pub psbt: &'psbt PartiallySignedTransaction,
    pub index: usize,
}

Psbt satisfier for at inputs at a particular index Takes in &psbt because multiple inputs will share the same psbt structure All operations on this structure will panic if index is more than number of inputs in pbst This does not support satisfaction for Covenant transactoins You are probably looking for finalizer::finalize method or PsbtCovInputSatisfier

Fields

psbt: &'psbt PartiallySignedTransaction

pbst

index: usize

input index

Implementations

impl<'psbt> PsbtInputSatisfier<'psbt>

pub fn new(psbt: &'psbt Psbt, index: usize) -> Self

Trait Implementations

impl<'psbt, Pk: MiniscriptKey + ToPublicKey> Satisfier<Pk> for PsbtInputSatisfier<'psbt>

fn lookup_tap_key_spend_sig(&self) -> Option<SchnorrSig>

Lookup the tap key spend sig

fn lookup_tap_leaf_script_sig( &self, pk: &Pk, lh: &TapLeafHash, ) -> Option<SchnorrSig>

Given a public key and a associated leaf hash, look up an schnorr signature with that key

fn lookup_raw_pkh_pk(&self, pkh: &Hash) -> Option<PublicKey>

Given a raw Pkh, lookup corresponding bitcoin::PublicKey

fn lookup_tap_control_block_map( &self, ) -> Option<&BTreeMap<ControlBlock, (Script, LeafVersion)>>
