Enum Curve25519Backend 

pub enum Curve25519Backend {
    Ifma,
    MulxAdx,
    Portable,
}

The implementation of GF(2^255 - 19) that X25519 and Ed25519 run on here.

A published vector passes whichever implementation runs, so it cannot tell which one did; this can.

Variants

Ifma

Four elements at once on AVX-512 IFMA (x86-64), for X25519 and, under std, Ed25519’s scalar multiplications; the MULX/ADX field for the rest.

MulxAdx

Four 64-bit limbs on MULX and ADX (x86-64).

Portable

The portable field: five 51-bit limbs, or ten of 26 and 25 bits on 32-bit RISC-V and under --cfg ic_limb32.
