#[must_use]pub fn sub_saturating_u16_m128i(a: m128i, b: m128i) -> m128i

This is supported with target feature sse2 only.

Lanewise saturating a - b with lanes as u16.

let a = m128i::from([51_u16, 61, 3, 4, u16::MAX, 2, 3, u16::MAX]);
let b = m128i::from([5_u16, 2, 71, 81, u16::MAX, 26, 37, u16::MIN]);
let c: [u16; 8] = sub_saturating_u16_m128i(a, b).into();
assert_eq!(c, [46, 59, 0, 0, 0, 0, 0, u16::MAX]);
