Enum curve25519_dalek::backend::vector::avx2::field::Shuffle

pub enum Shuffle {
    AAAA,
    BBBB,
    CACA,
    DBBD,
    ADDA,
    CBCB,
    ABAB,
    BADC,
    BACD,
    ABDC,
}

This is supported on crate feature simd_backend and (target features avx2 or avx512ifma) and target feature avx2 and non-target feature avx512ifma only.

The Shuffle enum represents a shuffle of a FieldElement2625x4.

The enum variants are named by what they do to a vector \( (A,B,C,D) \); for instance, Shuffle::BADC turns \( (A, B, C, D) \) into \( (B, A, D, C) \).
