    Complex32(Array<Complex<f32>, IxDyn>),
    Complex64(Array<Complex<f64>, IxDyn>),
}

A runtime-typed array whose element type is determined at runtime.

This is analogous to a Python numpy.ndarray where the dtype is a runtime property. Each variant wraps an Array<T, IxDyn> for the corresponding element type.

Use this when the element type is not known at compile time (e.g., loading from a file, receiving from Python/FFI).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
