Struct NumpyPositionArray 

pub struct NumpyPositionArray {
    pub data: Vec<f64>,
    pub shape: [usize; 2],
    pub dtype: String,
    pub c_order: bool,
}

A NumPy-compatible flat array descriptor for body positions.

Provides the data, shape, and dtype needed to reconstruct a NumPy array on the Python side via np.frombuffer or np.array.

Fields

data: Vec<f64>

Flat f64 data, row-major: [x0, y0, z0, x1, y1, z1, ...].

shape: [usize; 2]

Shape: [n_bodies, 3].

dtype: String

NumPy dtype string.

c_order: bool

Whether data is in C (row-major) order.
