Implementations
impl<Pk: MiniscriptKey> Descriptor<Pk>
[src]
pub fn translate_pk<Fpk, Fpkh, Q, E>(
&self,
translatefpk: Fpk,
translatefpkh: Fpkh
) -> Result<Descriptor<Q>, E> where
Fpk: FnMut(&Pk) -> Result<Q, E>,
Fpkh: FnMut(&Pk::Hash) -> Result<Q::Hash, E>,
Q: MiniscriptKey,
[src]
&self,
translatefpk: Fpk,
translatefpkh: Fpkh
) -> Result<Descriptor<Q>, E> where
Fpk: FnMut(&Pk) -> Result<Q, E>,
Fpkh: FnMut(&Pk::Hash) -> Result<Q::Hash, E>,
Q: MiniscriptKey,
Convert a descriptor using abstract keys to one using specific keys This will panic if translatefpk returns an uncompressed key when converting to a Segwit descriptor. To prevent this panic, ensure translatefpk returns an error in this case instead.
impl<Pk: MiniscriptKey + ToPublicKey> Descriptor<Pk>
[src]
pub fn address(&self, network: Network) -> Option<Address>
[src]
Computes the Bitcoin address of the descriptor, if one exists
pub fn script_pubkey(&self) -> Script
[src]
Computes the scriptpubkey of the descriptor
pub fn unsigned_script_sig(&self) -> Script
[src]
Computes the scriptSig that will be in place for an unsigned input spending an output with this descriptor. For pre-segwit descriptors, which use the scriptSig for signatures, this returns the empty script.
This is used in Segwit transactions to produce an unsigned transaction whose txid will not change during signing (since only the witness data will change).
pub fn witness_script(&self) -> Script
[src]
Computes the "witness script" of the descriptor, i.e. the underlying
script before any hashing is done. For Bare
, Pkh
and Wpkh
this
is the scriptPubkey; for ShWpkh
and Sh
this is the redeemScript;
for the others it is the witness script.
pub fn get_satisfication<S: Satisfier<Pk>>(
&self,
satisfier: S
) -> Result<(Vec<Vec<u8>>, Script), Error>
[src]
&self,
satisfier: S
) -> Result<(Vec<Vec<u8>>, Script), Error>
Returns satisfying witness and scriptSig to spend an output controlled by the given descriptor if it possible to construct one using the satisfier.
pub fn satisfy<S: Satisfier<Pk>>(
&self,
txin: &mut TxIn,
satisfier: S
) -> Result<(), Error>
[src]
&self,
txin: &mut TxIn,
satisfier: S
) -> Result<(), Error>
Attempts to produce a satisfying witness and scriptSig to spend an
output controlled by the given descriptor; add the data to a given
TxIn
output.
pub fn max_satisfaction_weight(&self) -> usize
[src]
Computes an upper bound on the weight of a satisfying witness to the transaction. Assumes all signatures are 73 bytes, including push opcode and sighash suffix. Includes the weight of the VarInts encoding the scriptSig and witness stack length.
pub fn script_code(&self) -> Script
[src]
Get the scriptCode
of a transaction output.
The scriptCode
is the Script of the previous transaction output being serialized in the
sighash when evaluating a CHECKSIG
& co. OP code.
impl Descriptor<DescriptorPublicKey>
[src]
pub fn derive(
&self,
child_number: ChildNumber
) -> Descriptor<DescriptorPublicKey>
[src]
&self,
child_number: ChildNumber
) -> Descriptor<DescriptorPublicKey>
Derives all wildcard keys in the descriptor using the supplied child_number
