Struct OrchardFvk 

pub struct OrchardFvk { /* private fields */ }

A key that provides the capability to view incoming and outgoing transactions.

This key is useful anywhere you need to maintain accurate balance, but do not want the ability to spend funds (such as a view-only wallet).

Defined in Zcash Protocol Spec § 4.2.3: Orchard Key Components.

Implementations

impl FullViewingKey

pub fn address_at( &self, j: impl Into<DiversifierIndex>, scope: Scope, ) -> Address

Returns the payment address for this key at the given index.

pub fn address(&self, d: Diversifier, scope: Scope) -> Address

Returns the payment address for this key corresponding to the given diversifier.

pub fn scope_for_address(&self, address: &Address) -> Option<Scope>

Returns the scope of the given address, or None if the address is not derived from this full viewing key.

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

where W: Write,

Serializes the full viewing key as specified in Zcash Protocol Spec § 5.6.4.4: Orchard Raw Full Viewing Keys

pub fn read<R>(reader: R) -> Result<FullViewingKey, Error>

where R: Read,

Parses a full viewing key from its “raw” encoding as specified in Zcash Protocol Spec § 5.6.4.4: Orchard Raw Full Viewing Keys

pub fn to_bytes(&self) -> [u8; 96]

Serializes the full viewing key as specified in Zcash Protocol Spec § 5.6.4.4: Orchard Raw Full Viewing Keys

pub fn from_bytes(bytes: &[u8; 96]) -> Option<FullViewingKey>

Parses a full viewing key from its “raw” encoding as specified in Zcash Protocol Spec § 5.6.4.4: Orchard Raw Full Viewing Keys

pub fn to_ivk(&self, scope: Scope) -> IncomingViewingKey

Derives an IncomingViewingKey for this full viewing key.

pub fn to_ovk(&self, scope: Scope) -> OutgoingViewingKey

Derives an OutgoingViewingKey for this full viewing key.

Trait Implementations

impl Clone for FullViewingKey

fn clone(&self) -> FullViewingKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FullViewingKey

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

Formats the value using the given formatter.

impl From<&ExtendedSpendingKey> for FullViewingKey

fn from(extsk: &ExtendedSpendingKey) -> FullViewingKey

Converts to this type from the input type.

impl From<&SpendingKey> for FullViewingKey

fn from(sk: &SpendingKey) -> FullViewingKey

Converts to this type from the input type.

impl Ord for FullViewingKey

fn cmp(&self, other: &FullViewingKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FullViewingKey

fn eq(&self, other: &FullViewingKey) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for FullViewingKey

fn partial_cmp(&self, other: &FullViewingKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
