Implementations

impl<K, P> JointKeyBuilder<P, K> where
    K: SecretKey + Mul<P, Output = P>,
    P: PublicKey<K = K>, 

pub fn new(n: usize) -> Result<JointKeyBuilder<P, K>, MuSigError>

Create a new JointKey instance containing no participant keys, or return TooManyParticipants if n exceeds MAX_SIGNATURES

pub fn num_signers(&self) -> usize

The number of parties in the Joint key

pub fn add_key(&mut self, pub_key: P) -> Result<usize, MuSigError>

Add a participant signer’s public key to the JointKey

pub fn key_exists(&self, key: &P) -> bool

Checks whether the given public key is in the participants list

pub fn is_full(&self) -> bool

Checks whether the number of pub_keys is equal to num_signers

pub fn add_keys<T: IntoIterator<Item = P>>(
    &mut self,
    keys: T
) -> Result<usize, MuSigError>

Add all the keys in keys to the participant list.

pub fn build<D: Digest>(self) -> Result<JointKey<P, K>, MuSigError>

Produce a sorted, immutable joint Musig public key from the gathered set of conventional public keys
