Provided Methods

fn swizzle2<T>( first: Simd<T, INPUT_LANES>, second: Simd<T, INPUT_LANES> ) -> Simd<T, OUTPUT_LANES>where T: SimdElement, LaneCount<INPUT_LANES>: SupportedLaneCount, LaneCount<OUTPUT_LANES>: SupportedLaneCount,

🔬This is a nightly-only experimental API. (portable_simd #86656)

从 first 和 second 的 lanes 创建一个新的 vector。

lane i 在 Self::INDEX[i] 为 First(j) 时为 first[j]，在 Second(j) 时为 second[j]。
