[−][src]

    pub unsafe fn _mm256_mask_testn_epi8_mask(
        k: __mmask32,
        a: __m256i,
        b: __m256i
    ) -> __mmask32

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512bw,avx512vl` only.
Expand description

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 (subject to writemask k) if the intermediate value is zero.
