Struct G2 

pub struct G2(/* private fields */);

A point on the BLS12-381 G2 curve.

Trait Implementations

impl AsRef<G2> for G2

fn as_ref(&self) -> &Self

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

impl Clone for G2

fn clone(&self) -> G2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for G2

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

Formats the value using the given formatter.

impl Display for G2

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

Formats the value using the given formatter.

impl Element for G2

fn zero() -> Self

Returns the additive identity.

fn one() -> Self

Returns the multiplicative identity.

fn add(&mut self, rhs: &Self)

Adds to self in-place.

fn mul(&mut self, rhs: &Scalar)

Multiplies self in-place.

impl FixedSize for G2

const SIZE: usize = 96usize

The size of the encoded value (in bytes).

impl Hash for G2

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 Ord for G2

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 G2

fn eq(&self, other: &G2) -> 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 G2

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 Point for G2

fn msm(points: &[Self], scalars: &[Scalar]) -> Self

Performs multi-scalar multiplication (MSM) on G2 points using Pippenger’s algorithm. Computes sum(scalars[i] * points[i]).

Filters out pairs where the point is the identity element (infinity). Returns an error if the lengths of the input slices mismatch.

fn map(&mut self, dst: DST, data: &[u8])

Maps the provided data to a group element.

impl Read for G2

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, _: &()) -> Result<Self, Error>

Reads a value from the buffer using the provided configuration cfg.

impl Write for G2

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

impl Copy for G2

impl Eq for G2

impl StructuralPartialEq for G2
