Struct Coordinate

pub struct Coordinate<E: Curve>(/* private fields */);

Affine coordinate of a point on elliptic curve

Implementations

impl<E: Curve> Coordinate<E>

pub fn as_be_bytes(&self) -> &[u8]

(Big-endian) bytes representation of a coordinate

pub fn from_be_bytes(bytes: &[u8]) -> Result<Self, InvalidCoordinate>

Parses (big-endian) bytes representation of a coordinate

pub fn to_scalar(&self) -> Scalar<E>

Converts coordinate into scalar (coordinate is reduced modulo curve order)

pub fn new(bytes: E::CoordinateArray) -> Self

Constructs a coordinate from a byte array

pub fn as_array(&self) -> &E::CoordinateArray

Bytes representation of a coordinate

Trait Implementations

impl<E: Curve> AsMut<[u8]> for Coordinate<E>

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<E: Curve> AsRef<[u8]> for Coordinate<E>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<E: Clone + Curve> Clone for Coordinate<E>

where E::CoordinateArray: Clone,

fn clone(&self) -> Coordinate<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Curve> Debug for Coordinate<E>

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

Formats the value using the given formatter.

impl<E: Curve> Default for Coordinate<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: Curve> Hash for Coordinate<E>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<E: Curve> Ord for Coordinate<E>

fn cmp(&self, other: &Self) -> 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<E: Curve> PartialEq for Coordinate<E>

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

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

const 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<E: Curve> PartialOrd for Coordinate<E>

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