Struct SpendValidatingKey 

pub struct SpendValidatingKey(/* private fields */);

A key used to validate spend authorization signatures.

Defined in Zcash Protocol Spec § 4.2.3: Orchard Key Components. Note that this is $\mathsf{ak}^\mathbb{P}$, which by construction is equivalent to $\mathsf{ak}$ but stored here as a RedPallas verification key.

Implementations

impl SpendValidatingKey

pub fn randomize(&self, randomizer: &Scalar) -> VerificationKey<SpendAuth>

Randomizes this spend validating key with the given randomizer.

pub fn to_bytes(&self) -> [u8; 32]

Converts this spend validating key to its serialized form, I2LEOSP_256(ak).

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Attempts to parse a byte slice as a spend validating key, I2LEOSP_256(ak).

Returns None if the given slice does not contain a valid spend validating key.

Trait Implementations

impl Clone for SpendValidatingKey

fn clone(&self) -> SpendValidatingKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpendValidatingKey

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

Formats the value using the given formatter.

impl From<&SpendAuthorizingKey> for SpendValidatingKey

fn from(ask: &SpendAuthorizingKey) -> Self

Converts to this type from the input type.

impl From<&SpendValidatingKey> for Point

fn from(spend_validating_key: &SpendValidatingKey) -> Point

Converts to this type from the input type.

impl From<FullViewingKey> for SpendValidatingKey

fn from(fvk: FullViewingKey) -> Self

Converts to this type from the input type.

impl Ord for SpendValidatingKey

fn cmp(&self, other: &SpendValidatingKey) -> 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 SpendValidatingKey

fn eq(&self, other: &Self) -> 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 SpendValidatingKey

fn partial_cmp(&self, other: &SpendValidatingKey) -> 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.
