Implementations

impl ExtendedFullViewingKey

pub fn read<R: Read>(reader: R) -> Result<Self>

pub fn write<W: Write>(&self, writer: W) -> Result<()>

pub fn address(&self, j: DiversifierIndex) -> Option<PaymentAddress>

Attempt to produce a payment address given the specified diversifier index, and return None if the specified index does not produce a valid diversifier.

pub fn find_address( &self, j: DiversifierIndex ) -> Option<(DiversifierIndex, PaymentAddress)>

Search the diversifier space starting at diversifier index j for one which will produce a valid diversifier, and return the payment address constructed using that diversifier along with the index at which the valid diversifier was found.

pub fn default_address(&self) -> (DiversifierIndex, PaymentAddress)

Returns the payment address corresponding to the smallest valid diversifier index, along with that index.

pub fn derive_internal(&self) -> Self

Derives an internal full viewing key used for internal operations such as change and auto-shielding. The internal FVK has the same spend authority (the private key corresponding to ak) as the original, but viewing authority only for internal transfers.

Specified in ZIP 32.

pub fn to_diversifiable_full_viewing_key(&self) -> DiversifiableFullViewingKey

Trait Implementations

impl Clone for ExtendedFullViewingKey

fn clone(&self) -> ExtendedFullViewingKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExtendedFullViewingKey

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

Formats the value using the given formatter.

impl From<&ExtendedFullViewingKey> for DiversifiableFullViewingKey

fn from(extfvk: &ExtendedFullViewingKey) -> Self

Converts to this type from the input type.

impl From<ExtendedFullViewingKey> for DiversifiableFullViewingKey

fn from(extfvk: ExtendedFullViewingKey) -> Self

Converts to this type from the input type.

impl PartialEq for ExtendedFullViewingKey

fn eq(&self, rhs: &ExtendedFullViewingKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
