    k: u8,
    a: __m256i
) -> __m256i
🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512cd,avx512vl only.
Expand description

Test each 32-bit element of a for equality with all other elements in a closer to the least significant bit using writemask k (elements are copied from src when the corresponding mask bit is not set). Each element’s comparison forms a zero extended bit vector in dst.
