Trait Implementations

impl<Pk: Clone + MiniscriptKey> Clone for Sh<Pk>

fn clone(&self) -> Sh<Pk>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Pk: MiniscriptKey> Debug for Sh<Pk>

impl<Pk: MiniscriptKey> DescriptorTrait<Pk> for Sh<Pk> where
    Pk: FromStr,
    Pk::Hash: FromStr,
    <Pk as FromStr>::Err: ToString,
    <<Pk as MiniscriptKey>::Hash as FromStr>::Err: ToString, 

fn sanity_check(&self) -> Result<(), Error>

Whether the descriptor is safe Checks whether all the spend paths in the descriptor are possible on the bitcoin network under the current standardness and consensus rules Also checks whether the descriptor requires signauture on all spend paths And whether the script is malleable. In general, all the guarantees of miniscript hold only for safe scripts. All the analysis guarantees of miniscript only hold safe scripts. The signer may not be able to find satisfactions even if one exists

fn address(&self, params: &'static AddressParams) -> Result<Address, Error> where
    Pk: ToPublicKey, 

Computes the Bitcoin address of the descriptor, if one exists Some descriptors like pk() don’t have any address.

fn script_pubkey(&self) -> Script where
    Pk: ToPublicKey, 

Computes the scriptpubkey of the descriptor

fn unsigned_script_sig(&self) -> Script where
    Pk: ToPublicKey, 

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.

fn explicit_script(&self) -> Script where
    Pk: ToPublicKey, 

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.

fn get_satisfaction<S>(
    &self,
    satisfier: S
) -> Result<(Vec<Vec<u8>>, Script), Error> where
    Pk: ToPublicKey,
    S: Satisfier<Pk>, 

Returns satisfying witness and scriptSig to spend an output controlled by the given descriptor if it possible to construct one using the satisfier S.

fn max_satisfaction_weight(&self) -> Result<usize, Error>

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. Returns Error when the descriptor is impossible to safisfy (ex: sh(OP_FALSE))

fn script_code(&self) -> Script where
    Pk: ToPublicKey, 

Get the scriptCode of a transaction output.

fn satisfy<S>(&self, txin: &mut TxIn, satisfier: S) -> Result<(), Error> where
    Pk: ToPublicKey,
    S: Satisfier<Pk>, 

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.
