    pub unsafe fn v128_store32_lane<const L: usize>(v: v128, m: *mut u32)

Available on `target_family="wasm"` and target feature `simd128` and WebAssembly only.
Expand description

Stores the 32-bit value from lane `L` of `v` into `m`

This intrinsic is provided for completeness and is equivalent to `*m = u32x4_extract_lane::<L>(v)` (which doesn’t require `unsafe`).

## §Unsafety

This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to store 4 bytes to. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned store.
