Implementations

impl EncryptedNumber

pub fn new(s: JubjubAffine, t: JubjubAffine) -> Self

Init encrypted number

pub fn encrypt(private_key: Fp, value: u32, random: Fp) -> Self

Enctypt number by private key

pub fn decrypt(&self, private_key: Fp) -> Option<u32>

Decrypt encrypted number by brute force

pub fn get_coordinate(self) -> (JubjubAffine, JubjubAffine)

Get left and right affine point

Trait Implementations

impl Add<EncryptedNumber> for EncryptedNumber

type Output = EncryptedNumber

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl CheckedAdd for EncryptedNumber

fn checked_add(&self, rhs: &Self) -> Option<Self>

Adds two numbers, checking for overflow. If overflow happens, None is returned.

impl CheckedSub for EncryptedNumber

fn checked_sub(&self, rhs: &Self) -> Option<Self>

Subtracts two numbers, checking for underflow. If underflow happens, None is returned.

impl Clone for EncryptedNumber

fn clone(&self) -> EncryptedNumber

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConfidentialTransferPublicInputs<TatePairing> for EncryptedNumber

fn init(s: JubjubAffine, t: JubjubAffine) -> Self

init transfer amount public

fn get(self) -> (JubjubAffine, JubjubAffine)

get s and t cypher text

impl Debug for EncryptedNumber

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

Formats the value using the given formatter.

impl Decode for EncryptedNumber

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for EncryptedNumber

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EncryptedNumber

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for EncryptedNumber

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq<EncryptedNumber> for EncryptedNumber

fn eq(&self, other: &EncryptedNumber) -> 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.

impl Serialize for EncryptedNumber

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub<EncryptedNumber> for EncryptedNumber

type Output = EncryptedNumber

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Copy for EncryptedNumber

impl EncodeLike<EncryptedNumber> for EncryptedNumber

impl Eq for EncryptedNumber

impl StructuralEq for EncryptedNumber

impl StructuralPartialEq for EncryptedNumber
