Required methods

pub fn random(rng: impl RngCore) -> Self[src]

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.

pub fn identity() -> Self[src]

Returns the additive identity, also known as the "neutral element".

pub fn generator() -> Self[src]

Returns a fixed generator of the prime-order subgroup.

pub fn is_identity(&self) -> Choice[src]

Determines if this point is the identity.

#[must_use]pub fn double(&self) -> Self[src]

Doubles this element.
