Expand description
This trait represents an element of a cryptographic group.
Associated Types
type Scalar: PrimeField
type Scalar: PrimeField
Scalars modulo the order of this group’s scalar field.
Required methods
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 is_identity(&self) -> Choice
fn is_identity(&self) -> Choice
Determines if this point is the identity.
