Function core::arch::wasm::v128_load32_lane
1.54.0 · source · pub unsafe fn v128_load32_lane<const L: usize>(v: v128, m: *const u32) -> v128

and target feature simd128
only.Expand description
Loads a 32-bit value from m
and sets lane L
of v
to that value.
This intrinsic is provided for completeness and is equivalent to
u32x4_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 4 bytes from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
