🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512vbmi,avx512vl only.
Expand description

Shuffle 8-bit integers in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
