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

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