Struct mask64x2 

pub struct mask64x2<S: Simd> { /* private fields */ }

A SIMD mask of 2 logical lanes corresponding to 64-bit vector elements.

The storage representation of this type is intentionally opaque and may vary depending on the SIMD level.

You can construct this mask type using the Self::splat, Self::from_bitmask, Self::from_slice, and Self::simd_from methods.

fn construct_mask<S: Simd>(simd: S) {
    // From a single boolean value:
    let a = mask64x2::splat(simd, true);
    let b = mask64x2::simd_from(simd, true);

    // From signed integer mask lanes:
    let c = mask64x2::from_slice(simd, &[-1, 0]);
    let d = mask64x2::simd_from(simd, [-1, 0]);

    // From a compact bitmask (same mask as above, least significant bit maps to lane 0):
    let e = mask64x2::from_bitmask(simd, 0b0001);

    // By setting individual lanes:
    let mut f = mask64x2::splat(simd, false);
    f.set(0, true);
}
