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.
