Struct wallet::LockScript

pub struct LockScript(_);

Script whose knowledge is required for spending some specific transaction output. This is the deepest nested version of Bitcoin script containing no hashes of other scripts, including P2SH redeemScript hashes or witnessProgram (hash or witness script), or public key hashes

Implementations

impl LockScript

pub fn extract_pubkeyset<Ctx>(
    &self
) -> Result<BTreeSet<PublicKey>, PubkeyParseError> where
    Ctx: ScriptContext, 

Returns set of unique public keys from the script; fails on public key hash

pub fn extract_pubkey_hash_set<Ctx>(
    &self
) -> Result<(BTreeSet<PublicKey>, BTreeSet<PubkeyHash>), PubkeyParseError> where
    Ctx: ScriptContext, 

Returns tuple of two sets: one for unique public keys and one for unique hash values, extracted from the script

pub fn extract_pubkeys_and_hashes<Ctx>(
    &self
) -> Result<(Vec<PublicKey>, Vec<PubkeyHash>), PubkeyParseError> where
    Ctx: ScriptContext, 

Returns tuple with two vectors: one for public keys and one for public key hashes present in the script; if any of the keys or hashes has more than a single occurrence it returns all occurrences for each of them

pub fn extract_pubkeys<Ctx>(&self) -> Result<Vec<PublicKey>, PubkeyParseError> where
    Ctx: ScriptContext, 

Returns all public keys found in the script; fails on public key hash. If the key present multiple times in the script it returns all occurrences.

pub fn replace_pubkeys<Ctx, Fpk>(
    &self,
    processor: Fpk
) -> Result<Self, PubkeyParseError> where
    Ctx: ScriptContext,
    Fpk: Fn(&PublicKey) -> PublicKey, 

Replaces pubkeys using provided matching function; does not fail on public key hashes.

pub fn replace_pubkeys_and_hashes<Ctx, Fpk, Fpkh>(
    &self,
    key_processor: Fpk,
    hash_processor: Fpkh
) -> Result<Self, PubkeyParseError> where
    Ctx: ScriptContext,
    Fpk: Fn(&PublicKey) -> PublicKey,
    Fpkh: Fn(&Hash) -> Hash, 

Replaces public keys and public key hashes using provided matching functions.
