Expand description
This trait represents an element of a cryptographic group.
Required Associated Types§
type Scalar: PrimeField
type Scalar: PrimeField
Scalars modulo the order of this group’s scalar field.
Required Methods§
fn random(rng: impl RngCore) -> Self
fn random(rng: impl RngCore) -> Self
Returns an element chosen uniformly at random from the non-identity elements of this group.
This function is non-deterministic, and samples from the user-provided RNG.
fn identity() -> Self
fn identity() -> Self
Returns the additive identity, also known as the “neutral element”.
fn generator() -> Self
fn generator() -> Self
Returns a fixed generator of the prime-order subgroup.
fn is_identity(&self) -> Choice
fn is_identity(&self) -> Choice
Determines if this point is the identity.
fn double(&self) -> Self
fn double(&self) -> Self
Doubles this element.
