The quadratic non-residue (17) used to construct the extension is
the same as that used in libff.

Base prime field underlying this extension.
source§fn mul_fp_by_nonresidue_in_place(fe: &mut Self::Fp) -> &mut Self::Fp
fn mul_fp_by_nonresidue_in_place(fe: &mut Self::Fp) -> &mut Self::Fp
Return
fe * Self::NONRESIDUE.
Intended for specialization when Self::NONRESIDUE has a special
structure that can speed up multiplicationsource§fn mul_fp_by_nonresidue_and_add(y: &mut Self::Fp, x: &Self::Fp)
fn mul_fp_by_nonresidue_and_add(y: &mut Self::Fp, x: &Self::Fp)
A specializable method for setting
y = x + NONRESIDUE * y.
This allows for optimizations when the non-residue is
canonically negative in the field.source§fn mul_fp_by_nonresidue_plus_one_and_add(y: &mut Self::Fp, x: &Self::Fp)
fn mul_fp_by_nonresidue_plus_one_and_add(y: &mut Self::Fp, x: &Self::Fp)
A specializable method for computing x + mul_fp_by_nonresidue(y) + y
This allows for optimizations when the non-residue is not -1.
source§fn sub_and_mul_fp_by_nonresidue(y: &mut Self::Fp, x: &Self::Fp)
fn sub_and_mul_fp_by_nonresidue(y: &mut Self::Fp, x: &Self::Fp)
A specializable method for computing x - mul_fp_by_nonresidue(y)
This allows for optimizations when the non-residue is
canonically negative in the field.
