Expand description

Trait describing a lookup table for signatures, hash preimages, etc. Every method has a default implementation that simply returns None on every query. Users are expected to override the methods that they have data for.

Provided Methods§

Source

fn lookup_ecdsa_sig(&self, _: &Pk) -> Option<ElementsSig>

Given a public key, look up an ECDSA signature with that key

Source

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

Lookup the tap key spend sig

Source

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

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

Source

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

Obtain a reference to the control block for a ver and script

Source

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

Given a raw Pkh, lookup corresponding bitcoin::PublicKey

Source

fn lookup_raw_pkh_x_only_pk(&self, _: &Hash) -> Option<XOnlyPublicKey>

Given a raw Pkh, lookup corresponding bitcoin::key::XOnlyPublicKey

Source

fn lookup_raw_pkh_ecdsa_sig(&self, _: &Hash) -> Option<(PublicKey, ElementsSig)>

Given a keyhash, look up the EC signature and the associated key Even if signatures for public key Hashes are not available, the users can use this map to provide pkh -> pk mapping which can be useful for dissatisfying pkh.

Source

fn lookup_raw_pkh_tap_leaf_script_sig( &self, _: &(Hash, TapLeafHash), ) -> Option<(XOnlyPublicKey, SchnorrSig)>

Given a keyhash, look up the schnorr signature and the associated key Even if signatures for public key Hashes are not available, the users can use this map to provide pkh -> pk mapping which can be useful for dissatisfying pkh.
