pub unsafe fn _mm512_mask_extractf64x4_pd<const IMM8: i32>(
    src: __m256d,
    k: u8,
    a: __m512d,
) -> __m256d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on x86-64 only.

Extract 256 bits (composed of 4 packed double-precision (64-bit) floating-point elements) from a, selected with imm8, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
