Struct ViewKey 

pub struct ViewKey { /* private fields */ }

Pair of a secret a and public b·G

The notes are encrypted against secret a, so this is used to decrypt the blinding factor and value

Implementations

impl ViewKey

pub fn new(a: Fr, B: ExtendedPoint) -> ViewKey

This method is used to construct a new ViewKey from the given pair of secret a and public b·G.

pub fn a(&self) -> &Fr

Gets a

pub fn B(&self) -> &ExtendedPoint

Gets B (b·G)

pub fn owns(&self, stealth_address: &StealthAddress) -> bool

Checks note_pk = H(R · a) · G + B

Trait Implementations

impl Archive for ViewKey

where Fr: Archive, ExtendedPoint: Archive,

type Archived = ArchivedViewKey

The archived representation of this type.

type Resolver = ViewKeyResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <ViewKey as Archive>::Resolver, out: *mut <ViewKey as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for ViewKey

fn clone(&self) -> ViewKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstantTimeEq for ViewKey

fn ct_eq(&self, other: &ViewKey) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for ViewKey

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

Formats the value using the given formatter.

impl<__D> Deserialize<ViewKey, __D> for <ViewKey as Archive>::Archived

where __D: Fallible + ?Sized, Fr: Archive, <Fr as Archive>::Archived: Deserialize<Fr, __D>, ExtendedPoint: Archive, <ExtendedPoint as Archive>::Archived: Deserialize<ExtendedPoint, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ViewKey, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl From<&SecretKey> for ViewKey

fn from(sk: &SecretKey) -> ViewKey

Converts to this type from the input type.

impl From<&ViewKey> for PublicKey

fn from(vk: &ViewKey) -> PublicKey

Converts to this type from the input type.

impl From<ViewKey> for PublicKey

fn from(vk: ViewKey) -> PublicKey

Converts to this type from the input type.

impl PartialEq for ViewKey

fn eq(&self, other: &ViewKey) -> 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 Serializable<64> for ViewKey

type Error = Error

The type returned in the event of a conversion error.

fn to_bytes(&self) -> [u8; 64]

Serialize Self into a [[u8; N]].

fn from_bytes( buf: &[u8; 64], ) -> Result<ViewKey, <ViewKey as Serializable<64>>::Error>

Deserialize a [&[u8; N]] into Self, it might be fail.

const SIZE: usize = N

The size of

impl<__S> Serialize<__S> for ViewKey

where __S: Fallible + ?Sized, Fr: Serialize<__S>, ExtendedPoint: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<ViewKey as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for ViewKey

impl Eq for ViewKey
