# [−][src]Function core::arch::wasm32::v16x8_shuffle

    pub unsafe fn v16x8_shuffle<const I0: usize, const I1: usize, const I2: usize, const I3: usize, const I4: usize, const I5: usize, const I6: usize, const I7: usize>(
        a: v128,
        b: v128
    ) -> v128

🔬 This is a nightly-only experimental API. (`wasm_simd` #74372)
This is supported on WebAssembly and target feature `simd128` only.

Same as `v8x16_shuffle`, except operates as if the inputs were eight 16-bit integers, only taking 8 indices to shuffle.

Indices in the range [0, 7] select from `a` while [8, 15] select from `b`. Note that this will generate the `v8x16.shuffle` instruction, since there is no native `v16x8.shuffle` instruction (there is no need for one since `v8x16.shuffle` suffices).
