Struct NonceKps 

pub struct NonceKps(/* private fields */);

A nonce key pair per batch-tree transaction output that we are a part of in the batch.

The musig::SecretNonce element of the tuple is an Option because it cannot be cloned or copied. When we are ready to sign a batch-tree transaction, we call the method take_sk to move out of the Option.

Implementations

impl NonceKps

pub fn take_sk(&mut self, txid: &Txid) -> Option<SecretNonce>

Take ownership of the musig::SecretNonce for the transaction identified by txid.

The caller must take ownership because the musig::SecretNonce ensures that it can only be used once, to avoid nonce reuse.

pub fn to_nonce_pks(&self) -> NoncePks

Convert into NoncePks.
