Expand description

Marker trait for types that may be used as SIMD vector elements.

Safety

This trait, when implemented, asserts the compiler can monomorphize #[repr(simd)] structs with the marked type as an element. Strictly, it is valid to impl if the vector will not be miscompiled. Practically, it is user-unfriendly to impl it if the vector won’t compile, even when no soundness guarantees are broken by allowing the user to try.
