Implementations§

§

impl<Pk, Ctx> SortedMultiVec<Pk, Ctx>
where Pk: MiniscriptKey, Ctx: ScriptContext,

pub fn new(k: usize, pks: Vec<Pk>) -> Result<SortedMultiVec<Pk, Ctx>, Error>

Create a new instance of SortedMultiVec given a list of keys and the threshold

Internally checks all the applicable size limits and pubkey types limitations according to the current Ctx.

pub fn from_tree(tree: &Tree<'_>) -> Result<SortedMultiVec<Pk, Ctx>, Error>
where Pk: FromStr, <Pk as FromStr>::Err: Display,

Parse an expression tree into a SortedMultiVec

pub fn translate_pk<T, Q, FuncError>( &self, t: &mut T ) -> Result<SortedMultiVec<Q, Ctx>, TranslateErr<FuncError>>
where T: Translator<Pk, Q, FuncError>, Q: MiniscriptKey,

This will panic if fpk returns an uncompressed key when converting to a Segwit descriptor. To prevent this panic, ensure fpk returns an error in this case instead.

pub fn k(&self) -> usize

The threshold value for the multisig.

pub fn n(&self) -> usize

The number of keys in the multisig.

pub fn pks(&self) -> &[Pk]

Accessor for the public keys in the multisig.

The keys in this structure might not be sorted. In general, they cannot be sorted until they are converted to consensus-encoded public keys, which may not be possible (for example for BIP32 paths with unfilled wildcards).

§

impl<Pk, Ctx> SortedMultiVec<Pk, Ctx>
where Pk: MiniscriptKey, Ctx: ScriptContext,

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

utility function to sanity a sorted multi vec

§

impl<Pk, Ctx> SortedMultiVec<Pk, Ctx>
where Pk: MiniscriptKey, Ctx: ScriptContext,

pub fn sorted_node(&self) -> Terminal<Pk, Ctx>
where Pk: ToPublicKey,

Create Terminal::Multi containing sorted pubkeys

pub fn encode(&self) -> ScriptBuf
where Pk: ToPublicKey,

Encode as a Bitcoin script

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

Attempt to produce a satisfying witness for the witness script represented by the parse tree

pub fn build_template<P>(&self, provider: &P) -> Satisfaction<Placeholder<Pk>>
where Pk: ToPublicKey, P: AssetProvider<Pk>,

Attempt to produce a witness template given the assets available

pub fn script_size(&self) -> usize

Size, in bytes of the script-pubkey. If this Miniscript is used outside of segwit (e.g. in a bare or P2SH descriptor), this quantity should be multiplied by 4 to compute the weight.

In general, it is not recommended to use this function directly, but to instead call the corresponding function on a Descriptor, which will handle the segwit/non-segwit technicalities for you.

pub fn max_satisfaction_witness_elements(&self) -> usize

Maximum number of witness elements used to satisfy the Miniscript fragment, including the witness script itself. Used to estimate the weight of the VarInt that specifies this number in a serialized transaction.

This function may panic on malformed Miniscript objects which do not correspond to semantically sane Scripts. (Such scripts should be rejected at parse time. Any exceptions are bugs.)

pub fn max_satisfaction_size(&self) -> usize

Maximum size, in bytes, of a satisfying witness. In general, it is not recommended to use this function directly, but to instead call the corresponding function on a Descriptor, which will handle the segwit/non-segwit technicalities for you.

All signatures are assumed to be 73 bytes in size, including the length prefix (segwit) or push opcode (pre-segwit) and sighash postfix.
