    pub unsafe fn v128_load16_lane<const L: usize>(v: v128, m: *const u16) -> v128

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

Loads a 16-bit value from `m` and sets lane `L` of `v` to that value.

This intrinsic is provided for completeness and is equivalent to `u16x8_replace_lane::<L>(v, *m)` (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 load 2 bytes from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
