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

Concatenate pairs of 16-byte blocks in a and b into a 32-byte temporary result, shift the result right by imm8 bytes, and store the low 16 bytes in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
