- * @brief Helper struct to enumerate through an ndarray *efficiently*.

- * NDIter nditer;
- * nditer.initialize(my_ndarray);
- * while (nditer.has_element()) {

- *    print(*((double *) nditer.element))
- *
- *    nditer.next(); // Go to next element.
- * }

-/// # Prerequisites
-///
-/// In order to derive from [`StructFields`], you must implement (or derive) [`Eq`] and [`Copy`] as required by
-/// `StructFields`.
-///
-/// Moreover, `#[derive(StructFields)]` can only be used for `struct`s with named fields, and may only contain fields
-/// with either `StructField` or [`PhantomData`] types.
-///
-/// # Attributes for [`StructFields`]
-///
-/// Each `StructField` field must be declared with the `#[value_type(...)]` attribute. The argument of `value_type`
-/// accepts one of the following:
-///
-/// - An expression returning an instance of `inkwell::types::BasicType` (with or without the receiver `ctx`/`context`).
-/// For example, `context.i8_type()`, `ctx.i8_type()`, and `i8_type()` all refer to `i8`.
-/// - The reserved identifiers `usize` and `size_t` referring to an `inkwell::types::IntType` of the platform-dependent
-/// integer size. `usize` and `size_t` can also be used as the receiver to other method calls, e.g.
-/// `usize.array_type(3)`.
-///
-/// # Example
-///
-/// The following is an example of an LLVM slice implemented using `#[derive(StructFields)]`.
-///
-/// ```rust,ignore
-/// use nac3core::{
-///     codegen::types::structure::StructField,
-///     inkwell::{
-///         values::{IntValue, PointerValue},
-///         AddressSpace,
-///     },
-/// };
-/// use nac3core_derive::StructFields;
-///
-/// // All classes that implement StructFields must also implement Eq and Copy
-/// #[derive(PartialEq, Eq, Clone, Copy, StructFields)]
-/// pub struct SliceValue<'ctx> {
-///     // Declares ptr have a value type of i8*
-///     //
-///     // Can also be written as `ctx.i8_type().ptr_type(...)` or `context.i8_type().ptr_type(...)`
-///     #[value_type(i8_type().ptr_type(AddressSpace::default()))]
-///     ptr: StructField<'ctx, PointerValue<'ctx>>,
-///
-///     // Declares len have a value type of usize, depending on the target compilation platform
-///     #[value_type(usize)]
-///     len: StructField<'ctx, IntValue<'ctx>>,
-/// }
-/// ```

-//! This module contains abstraction over all intrinsic composite types of NAC3.

-//! # `raw_alloca` vs `alloca` vs `construct`
-//!
-//! There are three ways of creating a new object instance using the abstractions provided by this
-//! module.
-//!
-//! - `raw_alloca`: Allocates the object on the stack, returning an instance of
-//!   [`impl BasicValue`][inkwell::values::BasicValue]. This is similar to a `malloc` expression in
-//!   C++ but the object is allocated on the stack.
-//! - `alloca`: Similar to `raw_alloca`, but also wraps the allocated object with
-//!   [`<Self as ProxyType<'ctx>>::Value`][ProxyValue], and returns the wrapped object. The returned
-//!   object will not initialize any value or fields. This is similar to a type-safe `malloc`
-//!   expression in C++ but the object is allocated on the stack.
-//! - `construct`: Similar to `alloca`, but performs some initialization on the value or fields of
-//!   the returned object. This is similar to a `new` expression in C++ but the object is allocated
-//!   on the stack.
