Function core::arch::x86_64::_mm512_mask_cvtsepi16_epi8

pub unsafe fn _mm512_mask_cvtsepi16_epi8(
    src: __m256i, 
    k: __mmask32, 
    a: __m512i
) -> __m256i

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

Available on x86-64 and target feature avx512bw only.

Convert packed signed 16-bit integers in a to packed 8-bit integers with signed saturation, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
