Implementations

impl<Pk: MiniscriptKey> Sh<Pk>

pub fn into_inner(self) -> ShInner<Pk>

Get the Inner

pub fn as_inner(&self) -> &ShInner<Pk>

Create a new p2sh sortedmulti descriptor with threshold k and Vec of pks.

pub fn new_wsh(ms: Miniscript<Pk, Segwitv0>) -> Result<Self, Error>

Create a new p2sh wrapped wsh descriptor with the raw miniscript

pub fn new_with_wsh(wsh: Wsh<Pk>) -> Self

Create a new p2sh wrapper for the given wsh descriptor

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

Checks whether the descriptor is safe.

pub fn new_wsh_sortedmulti(k: usize, pks: Vec<Pk>) -> Result<Self, Error>

Create a new p2sh wrapped wsh sortedmulti descriptor from threshold k and Vec of pks

pub fn new_wpkh(pk: Pk) -> Result<Self, Error>

Create a new p2sh wrapped wpkh from Pk

pub fn new_with_wpkh(wpkh: Wpkh<Pk>) -> Self

Create a new p2sh wrapper for the given wpkh descriptor

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

Computes an upper bound on the weight of a satisfying witness to the transaction.

Assumes all ec-signatures are 73 bytes, including push opcode and sighash suffix. Includes the weight of the VarInts encoding the scriptSig and witness stack length.

Errors

When the descriptor is impossible to safisfy (ex: sh(OP_FALSE)).

impl<Pk: MiniscriptKey + ToPublicKey> Sh<Pk>

pub fn script_pubkey(&self) -> Script

Obtains the corresponding script pubkey for this descriptor.

pub fn address(&self, network: Network) -> Address

Obtains the corresponding address for this descriptor.

pub fn inner_script(&self) -> Script

Obtain the underlying miniscript for this descriptor

pub fn ecdsa_sighash_script_code(&self) -> Script

Obtains the pre bip-340 signature script code for this descriptor.

pub fn unsigned_script_sig(&self) -> Script

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

Returns satisfying non-malleable witness and scriptSig with minimum weight to spend an output controlled by the given descriptor if it is possible to construct one using the satisfier.

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

Returns satisfying, possibly malleable, witness and scriptSig with minimum weight to spend an output controlled by the given descriptor if it is possible to construct one using the satisfier.
