Struct RoundSecretNonces 

pub struct RoundSecretNonces { /* private fields */ }

In-memory store for MuSig2 secret cosign nonces used during round signing. Entries are keyed by the first cosign pubkey of each round attempt — that pubkey is freshly generated in [start_attempt], uniquely identifies the attempt within a process, and is reachable from the persisted AttemptState::AwaitingUnsignedVtxoTree.

Nonces never touch disk: persisting them risks signing twice with the same nonce, which is unsafe with MuSig2.

Implementations

impl RoundSecretNonces

pub fn new() -> Self

pub fn stash( &self, first_cosign_pubkey: PublicKey, nonces: Vec<Vec<SecretNonce>>, )

Insert nonces under the given key, replacing any previous entry.

pub fn take( &self, first_cosign_pubkey: &PublicKey, ) -> Option<Vec<Vec<SecretNonce>>>

Remove and return the nonces stashed under the given key. None after a process restart or if the entry was never stashed.

pub fn forget(&self, first_cosign_pubkey: &PublicKey)

Drop the entry under the given key without returning its contents. Use when a stashed attempt is being replaced by a new one and its key would otherwise be unreachable.

Trait Implementations

impl Default for RoundSecretNonces

fn default() -> RoundSecretNonces

Returns the “default value” for a type.
