Implementations§

Source§

impl<Ivk, Nk, AccountId> ScanningKey<Ivk, Nk, AccountId>

Source

pub fn new( ivk: Ivk, nk: Option<Nk>, account_id: AccountId, key_scope: Option<Scope>, ) -> Self

Constructs a new ScanningKey from its constituent parts.

Trait Implementations§

Source§

impl<AccountId> ScanningKeyOps<NoteEncryptionDomain<IronwoodVersion>, AccountId, Nullifier> for ScanningKey<IncomingViewingKey, FullViewingKey, AccountId>

Available on crate feature orchard only.

An Orchard viewing key trial-decrypts Ironwood outputs under the Ironwood note-encryption domain. The key material is the same as for Orchard; only the domain (and thus the accepted note plaintext version) differs.

Source§

fn prepare(&self) -> PreparedIncomingViewingKey

Prepare the key for use in batch trial decryption.
Source§

fn nf(&self, note: &Note, _position: Position) -> Option<Nullifier>

Produces the nullifier for the specified note and witness, if possible. Read more
Source§

fn account_id(&self) -> &AccountId

Returns the account identifier for this key. An account identifier corresponds to at most a single unified spending key’s worth of spend authority, such that both received notes and change spendable by that spending authority will be interpreted as belonging to that account.
Source§

fn key_scope(&self) -> Option<Scope>

Returns the [zip32::Scope] for which this key was derived, if known.

Source§

fn key_scope(&self) -> Option<Scope>
