Trait Implementations

impl Additive for Point

fn add(a: &Self, b: &Self) -> Self

Computes a + b

fn sub(a: &Self, b: &Self) -> Self

Computes a - b

fn negate(x: &Self) -> Self

Computes -a

fn double(x: &Self) -> Self

where Self: Sized,

Takes x, returns x + x

impl Clone for Point

fn clone(&self) -> Point

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CompressedEncoding for Point

type Bytes = [u8; 32]

Byte array that fits the whole compressed point representation

fn to_bytes_compressed(&self) -> Self::Bytes

Encodes the point as bytes in compressed form

impl ConditionallySelectable for Point

fn conditional_select(a: &Self, b: &Self, choice: Choice) -> Self

Select a or b according to choice.

fn conditional_assign(&mut self, other: &Self, choice: Choice)

Conditionally assign other to self, according to choice.

fn conditional_swap(a: &mut Self, b: &mut Self, choice: Choice)

Conditionally swap self and other if choice == 1; otherwise, reassign both unto themselves.

impl ConstantTimeEq for Point

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

Determine if two items are equal.

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

Determine if two items are NOT equal.

impl Decode for Point

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

Decodes a point from its compressed or uncompressed representation

impl Default for Point

fn default() -> Self

Returns the “default value” for a type.

impl From<CurveGenerator> for Point

fn from(_: CurveGenerator) -> Self

Converts to this type from the input type.

impl Hash for Point

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 Multiplicative<Point> for Scalar

type Output = Point

Type of multiplication output

fn mul(a: &Self, b: &Point) -> Self::Output

Computes a * b

impl OnCurve for Point

fn is_on_curve(&self) -> Choice

Checks whether the point is on curve

impl Ord for Point

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 PartialEq for Point

fn eq(&self, other: &Point) -> 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 PartialOrd for Point

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.

impl SmallFactor for Point

fn is_torsion_free(&self) -> Choice

Checks whether a point has no small factor

impl UncompressedEncoding for Point

type Bytes = <Point as CompressedEncoding>::Bytes

Byte array that fits the whole uncompressed point representation

fn to_bytes_uncompressed(&self) -> Self::Bytes

Encodes the point as bytes in uncompressed form

impl Zero for Point

fn zero() -> Self

Constructs zero value of Self

fn is_zero(x: &Self) -> Choice

Checks (in constant-time) if x is zero

impl Zeroize for Point

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Copy for Point

impl Eq for Point

impl StructuralPartialEq for Point
