Trait Implementations

impl Clone for G1

fn clone(&self) -> G1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for G1

impl CurveProjective for G1

type Engine = Bls12

type Scalar = Fr

type Base = Fq

type Affine = G1Affine

fn random<R: RngCore>(rng: &mut R) -> Self

Generate a random curve point.

fn zero() -> Self

Returns the additive identity.

fn one() -> Self

Returns a fixed generator of unknown exponent.

fn is_zero(&self) -> bool

Determines if this point is the point at infinity.

fn is_normalized(&self) -> bool

Checks if the point is already "normalized" so that cheap affine conversion is possible.

fn batch_normalization(v: &mut [Self])

Normalizes a slice of projective elements so that conversion to affine is cheap.

fn double(&mut self)

Doubles this element.

fn add_assign(&mut self, other: &Self)

Adds another element to this element.

fn add_assign_mixed(&mut self, other: &Self::Affine)

Adds an affine element to this element.

fn negate(&mut self)

Negates this element.

fn mul_assign<S: Into<<Self::Scalar as PrimeField>::Repr>>(&mut self, other: S)

Performs scalar multiplication of this element.

fn into_affine(&self) -> G1Affine

Converts this element into its affine representation.

fn recommended_wnaf_for_scalar(
    scalar: <Self::Scalar as PrimeField>::Repr
) -> usize

Recommends a wNAF window table size given a scalar. Always returns a number between 2 and 22, inclusive.

fn recommended_wnaf_for_num_scalars(num_scalars: usize) -> usize

Recommends a wNAF window size given the number of scalars you intend to multiply a base by. Always returns a number between 2 and 22, inclusive.

fn as_tuple(&self) -> (&Fq, &Fq, &Fq)

Borrow references to the X, Y, and Z coordinates of this point.

unsafe fn as_tuple_mut(&mut self) -> (&mut Fq, &mut Fq, &mut Fq)

Borrow mutable references to the X, Y, and Z coordinates of this point. Unsafe, because incorrectly modifying the coordinates violates the guarantee that the point must be on the curve and in the correct subgroup.

fn sub_assign(&mut self, other: &Self)

Subtracts another element from this element.

fn sub_assign_mixed(&mut self, other: &Self::Affine)

Subtracts an affine element from this element

impl Debug for G1

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

Formats the value using the given formatter.

impl Default for G1

fn default() -> Self

Returns the "default value" for a type.

impl Display for G1

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

Formats the value using the given formatter.

impl Eq for G1

impl From<G1> for G1Affine

fn from(p: G1) -> G1Affine

Performs the conversion.

impl From<G1Affine> for G1

fn from(p: G1Affine) -> G1

Performs the conversion.

impl PartialEq<G1> for G1

fn eq(&self, other: &G1) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl SerDes for G1

fn serialize<W: Write>(&self, writer: &mut W, compressed: bool) -> Result<()>

Convert a G1 point to a blob.

fn deserialize<R: Read>(reader: &mut R, compressed: bool) -> Result<Self>

Deserialize a G1 element from a blob. Returns an error if deserialization fails.

impl StructuralEq for G1

impl Zeroize for G1

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.
