Struct PublicKey 

pub struct PublicKey { /* private fields */ }

Implementations

impl PublicKey

pub fn x(&self) -> Fr

pub fn y(&self) -> Fr

pub fn new_unchecked(x: Fr, y: Fr) -> Self

Caller must ensure the point is on the BJJ curve and in the prime-order subgroup.

impl PublicKey

pub fn from_coordinates(x: Fr, y: Fr) -> Result<Self, CryptoError>

Construct from coordinates with on-curve and subgroup membership validation.

pub fn is_on_curve(&self) -> bool

Check: A*x^2 + y^2 == 1 + D*x^2*y^2

pub fn add(&self, other: &Self) -> Result<Self, CryptoError>

Twisted Edwards point addition (complete – no exceptional cases).

pub fn mul_scalar(&self, scalar_le_bytes: &[u8]) -> Result<Self, CryptoError>

Constant-time double-and-add scalar multiplication. Scalar is little-endian bytes.

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

Compressed encoding: LE y-coordinate with sign bit in MSB.

pub fn to_hex(&self) -> String

pub fn from_hex(hex_str: &str) -> Result<Self, CryptoError>

Decompress from hex with full validation (curve check + subgroup membership).

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PublicKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PublicKey

fn eq(&self, other: &PublicKey) -> 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 Serialize for PublicKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PublicKey
