Interface IntoPyArray

src/convert.rs:37–45

Conversion trait from owning Rust types into [`PyArray`]. This trait takes ownership of `self`, which means it holds a pointer into the Rust heap. In addition, some destructive methods like `resize` cannot be used with NumPy arrays constructed using this trait. # Example ``` use numpy::{PyArray, IntoPyArray, PyArrayMethods}; use pyo3::Python; Python::attach(|py| { let py_array = vec![1, 2, 3]

/// });
/// ```
pub trait IntoPyArray: Sized {
    /// The element type of resulting array.
    type Item: Element;
    /// The dimension type of the resulting array.
    type Dim: Dimension;

    /// Consumes `self` and moves its data into a NumPy array.
    fn into_pyarray<'py>(self, py: Python<'py>) -> Bound<'py, PyArray<Self::Item, Self::Dim>>;
}

impl<T: Element> IntoPyArray for Box<[T]> {
    type Item = T;
