# Function core::arch::x86::_mm_testn_epi8_mask
[−][src]

    pub unsafe fn _mm_testn_epi8_mask(a: __m128i, b: __m128i) -> __mmask16

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512bw,avx512vl` only.

Compute the bitwise NAND of packed 8-bit integers in a and b, producing intermediate 8-bit values, and set the corresponding bit in result mask k if the intermediate value is zero.
