Implementations

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

pub fn new(
    k: usize,
    pks: Vec<Pk, Global>
) -> 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: ToString,

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.

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) -> ScriptBufwhere
    Pk: ToPublicKey,

Encode as a Bitcoin script

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