    pub unsafe fn simd_masked_store<V, U, T>(mask: V, ptr: U, val: T)

🔬This is a nightly-only experimental API. (`core_intrinsics`)
Expand description

Writes to a vector of pointers.

`T` must be a vector.

`U` must be a pointer to the element type of `T`

`V` must be a vector of integers with the same length as `T` (but any element size).

For each element, if the corresponding value in `mask` is `!0`, write the corresponding value in `val` to the pointer offset from `ptr`. The first element is written to `ptr`, the second to `ptr.wrapping_offset(1)` and so on. Otherwise if the corresponding value in `mask` is `0`, do nothing.

## §Safety

Unmasked values in `T` must be writeable as if by `<ptr>::write` (e.g. aligned to the element type).

`mask` must only contain `0` or `!0` values.
