# Function core::arch::wasm32::i16x8_narrow_i32x4_s[−][src]

    pub unsafe fn i16x8_narrow_i32x4_s(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.

Converts two input vectors into a smaller lane vector by narrowing each lane.

Signed saturation to 0x7fff or 0x8000 is used and the input lanes are always interpreted as signed integers.
