source ·
pub struct SubgroupPoint(_);
Expand description

This represents a point in the prime-order subgroup of Jubjub, in extended coordinates.

Implementations§

source§

impl SubgroupPoint

source

pub const fn from_raw_unchecked(u: Fq, v: Fq) -> Self

Constructs an AffinePoint given u and v without checking that the point is on the curve or in the prime-order subgroup.

This should only be used for hard-coding constants (e.g. fixed generators); in all other cases, use SubgroupPoint::from_bytes instead.
