# Function core::arch::x86_64::_mm256_mask_cmpeq_epu64_mask
[−][src]

    pub unsafe fn _mm256_mask_cmpeq_epu64_mask(
        k1: __mmask8,
        a: __m256i,
        b: __m256i
    ) -> __mmask8

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f,avx512vl` only.
Expand description

Compare packed unsigned 64-bit integers in a and b for equality, and store the results in mask vector k using zeromask k1 (elements are zeroed out when the corresponding mask bit is not set).
