Function core::arch::x86_64::_mm256_mask_cvtusepi64_epi8

pub unsafe fn _mm256_mask_cvtusepi64_epi8(
    src: __m128i, 
    k: __mmask8, 
    a: __m256i
) -> __m128i

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Available on x86-64 and target feature avx512f,avx512vl only.

Convert packed unsigned 64-bit integers in a to packed unsigned 8-bit integers with unsigned saturation, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
