/// A vector-like container that does not store its length directly, but rather retrieves them through inner options
/// I highly discourage using this if `size_of::<Yourtype>` != `size_of::<Option<Yourtype>>`
// # Guidance for the Layout of this type:
// The inner array must never be fragmented/sparse.
// It must either be filled with None, or start with a contiguous section of Some, followed exclusively by None.
// Not covering this requirement means member functions will unexpectedly panic or produce UB in the future.
