type ProjectivePoint = ProjectivePoint<TinyCurve64>

Elliptic curve point in projective coordinates.

impl Debug for TinyCurve64

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

Formats the value using the given formatter.

impl Default for TinyCurve64

fn default() -> TinyCurve64

Returns the “default value” for a type.

impl DigestPrimitive for TinyCurve64

Available on crate feature ecdsa only.

type Digest = TinyHash<8>

Preferred digest to use when computing ECDSA signatures for this elliptic curve. This is typically a member of the SHA-2 family.

impl FieldBytesEncoding<TinyCurve64> for <TinyCurve64 as Curve>::Uint

fn decode_field_bytes( field_bytes: &GenericArray<u8, <C as Curve>::FieldBytesSize>, ) -> Self

Decode unsigned integer from serialized field element.

fn encode_field_bytes(&self) -> GenericArray<u8, <C as Curve>::FieldBytesSize>

Encode unsigned integer into serialized field element.

impl Ord for TinyCurve64

fn cmp(&self, other: &TinyCurve64) -> 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 TinyCurve64

fn eq(&self, other: &TinyCurve64) -> 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 PartialOrd for TinyCurve64

fn partial_cmp(&self, other: &TinyCurve64) -> 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 PointCompression for TinyCurve64

const COMPRESS_POINTS: bool = true

Should point compression be applied by default?

impl PrimeCurveParams for TinyCurve64

const EQUATION_A: Self::FieldElement = {transmute(0xfffffffffffffc7c): <curve64::TinyCurve64 as primeorder::PrimeCurveParams>::FieldElement}

Coefficient a in the curve equation.

const EQUATION_B: Self::FieldElement = {transmute(0x0000000000000006): <curve64::TinyCurve64 as primeorder::PrimeCurveParams>::FieldElement}

Coefficient b in the curve equation.

const GENERATOR: (Self::FieldElement, Self::FieldElement)

Generator point’s affine coordinates: (x, y).

type FieldElement = FieldElement<u64, FIELD_MODULUS>

Base field element type.

type PointArithmetic = EquationAIsMinusThree

Point arithmetic implementation, might be optimized for this specific curve

impl VerifyPrimitive<TinyCurve64> for AffinePoint<TinyCurve64>
