Struct f32x16 

#[repr(C, align(64))]
pub struct f32x16<S: Simd> {
    pub(crate) val: S::f32x16,
    pub simd: S,
}

A SIMD vector of 16 f32 elements.

You may construct this vector type using the Self::splat, Self::from_slice, Self::simd_from, Self::from_fn, and Self::block_splat methods.

fn construct_simd<S: Simd>(simd: S) {
    // From a single scalar value:
    let a = f32x16::splat(simd, 1.0);
    let b = f32x16::simd_from(simd, 1.0);

    // From a slice:
    let c = f32x16::from_slice(simd, &[1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0]);

    // From an array:
    let d = f32x16::simd_from(simd, [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0]);

    // From an element-wise function:
    let e = f32x16::from_fn(simd, |i| i as f32);
    // From `Self::Block`:
    let f = f32x16::block_splat(f32x4::simd_from(simd, [1.0, 2.0, 3.0, 4.0]));
}

On x86 platforms, this operation will still be slower than converting to i32, because there is no native instruction for converting to u32 (at least until AVX-512, which is currently not supported). If you know your values fit within range of an i32, you should convert to an i32 and cast to your desired datatype afterwards.
