Struct v128
#[repr(simd)]
pub struct v128(pub(in ::core_arch::wasm32::simd128) [i32; 4]);WASM-specific 128-bit wide SIMD vector type.
This type corresponds to the v128 type in the WebAssembly SIMD
proposal. This type is 128-bits
large and the meaning of all the bits is defined within the context of
how this value is used.
This same type is used simultaneously for all 128-bit-wide SIMD types, for example:
- sixteen 8-bit integers (both
i8andu8) - eight 16-bit integers (both
i16andu16) - four 32-bit integers (both
i32andu32) - two 64-bit integers (both
i64andu64) - four 32-bit floats (
f32) - two 64-bit floats (
f64)
The v128 type in Rust is intended to be quite analogous to the v128
type in WebAssembly. Operations on v128 can only be performed with the
functions in this module.

Implementations
impl v128
fn splat(value: i32) -> v128Put the same value in every lane.
