Enum VecTy 

pub enum VecTy {
    M128,
    M128i,
    M128d,
    M256,
    M256i,
    M256d,
    M512,
    M512i,
    M512d,
    M128bh,
    M256bh,
    M512bh,
    M128h,
    M256h,
    M512h,
}

Which x86 vector type a Ty::Vector is.

The name is the same in C and in core::arch, which is the whole point: the generated Rust says ::core::arch::x86_64::__m128i and Rust’s type has the size, the alignment and the calling convention C’s has.

Variants

M128

__m128: four float lanes.

M128i

__m128i: sixteen bytes of integer lanes, whatever width.

M128d

__m128d: two double lanes.

M256

__m256: eight float lanes.

M256i

__m256i: thirty-two bytes of integer lanes.

M256d

__m256d: four double lanes.

M512

__m512: sixteen float lanes (AVX-512).

M512i

__m512i: sixty-four bytes of integer lanes.

M512d

__m512d: eight double lanes.

M128bh

__m128bh, __m256bh, __m512bh: bfloat16 lanes (AVX512-BF16). C only moves them between intrinsics; no scalar __bf16 is needed.

M256bh

See VecTy::M128bh.

M512bh

See VecTy::M128bh.

M128h

__m128h, __m256h, __m512h: half-precision lanes (AVX512-FP16), opaque in the same way: no _Float16 scalar is needed.

M256h

See VecTy::M128h.

M512h

See VecTy::M128h.

Implementations

impl VecTy

pub fn name(self) -> &'static str

The name, which C and core::arch spell the same way.

pub fn bytes(self) -> u64

sizeof, which is also _Alignof: a vector type is aligned to its own width on every x86 ABI, and so is Rust’s.
