Struct EncryptedLinkSnapshot 

pub struct EncryptedLinkSnapshot { /* private fields */ }

Serializable snapshot of an established EncryptedLink.

Serialize with serialize and restore with restore_encrypted_link. Snapshot bytes include sensitive key material and must be stored as secrets.

Implementations

impl EncryptedLinkSnapshot

pub fn serialize(&self) -> Vec<u8>

Serialize to a compact binary format for durable storage.

The output contains the pubky-noise session state followed by the counterparty’s 32-byte Noise public key and 72-byte recovery context.

pub fn deserialize(bytes: &[u8]) -> Result<Self>

Deserialize from bytes previously produced by serialize.

Returns PaykitError::InvalidData if the bytes are malformed or the embedded public key cannot be reconstructed.

pub fn recipient(&self) -> &PublicKey

Access the counterparty’s public key embedded in the snapshot.

pub fn remote_noise_public_key(&self) -> &PublicKey

Access the counterparty’s identity-wide Noise public key.

pub fn recovery_context(&self) -> &EncryptedLinkRecoveryContext

Recovery attempts used to derive this connection’s stream paths.

pub fn link_id(&self) -> Option<[u8; 32]>

Stable identifier of the completed Noise handshake, unchanged by transport messages.

pub async fn has_pending_private_application_message( &self, public_storage: &PublicStorage, local_identity_public_key: &PublicKey, local_noise_secret_key: &[u8; 32], ) -> Result<bool>

Check whether the next private message slot exists without restoring Noise.

This is an advisory HEAD request. It does not authenticate a message or advance the snapshot. Before receiving, reload the authoritative state and use the ordinary locked receive workflow. Session authorization and key rotation remain the caller’s responsibility.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
