Struct Pkh

pub struct Pkh<Pk: MiniscriptKey> { /* private fields */ }

A bare PkH descriptor at top level

Implementations

impl<Pk: MiniscriptKey> Pkh<Pk>

pub fn new(pk: Pk) -> Result<Self, ScriptContextError>

Create a new Pkh descriptor

pub fn as_inner(&self) -> &Pk

Get a reference to the inner key

pub fn into_inner(self) -> Pk

Get the inner key

pub fn max_weight_to_satisfy(&self) -> Weight

Computes an upper bound on the difference between a non-satisfied TxIn’s segwit_weight and a satisfied TxIn’s segwit_weight

Since this method uses segwit_weight instead of legacy_weight, if you want to include only legacy inputs in your transaction, you should remove 1WU from each input’s max_weight_to_satisfy for a more accurate estimate.

Assumes all ECDSA signatures are 73 bytes, including push opcode and sighash suffix.

Errors

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

pub fn max_satisfaction_weight(&self) -> usize

👎Deprecated since 10.0.0: Use max_weight_to_satisfy instead. The method to count bytes was redesigned and the results will differ from max_weight_to_satisfy. For more details check rust-bitcoin/rust-miniscript#476.

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.

pub fn get_satisfaction<S>( &self, satisfier: S, ) -> Result<(Vec<Vec<u8>>, ScriptBuf), 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.

where P: AssetProvider<DefiniteDescriptorKey>,

Returns a plan if the provided assets are sufficient to produce a malleable satisfaction
