Trait ScanningKeyOps 

pub trait ScanningKeyOps<D: Domain, Nf> {
    // Required methods
    fn prepare(&self) -> D::IncomingViewingKey;
    fn account_id(&self) -> &AccountId;
    fn key_scope(&self) -> Option<Scope>;
    fn nf(&self, note: &D::Note, note_position: Position) -> Option<Nf>;
}

A key that can be used to perform trial decryption and nullifier computation for a CompactSaplingOutput or CompactOrchardAction.

Required Methods

fn prepare(&self) -> D::IncomingViewingKey

Prepare the key for use in batch trial decryption.

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.

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

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

fn nf(&self, note: &D::Note, note_position: Position) -> Option<Nf>

Produces the nullifier for the specified note and witness, if possible.

IVK-based implementations of this trait cannot successfully derive nullifiers, in which this function will always return None.
