Trait ArrayElement

pub trait ArrayElement: Sized + Sealed {
    const DTYPE: Dtype;

    // Required methods
    fn array_item(array: &Array) -> Result<Self>;
    fn array_data(array: &Array) -> *const Self;
}

A marker trait for array elements.

Required Associated Constants

const DTYPE: Dtype

The data type of the element.

Required Methods

fn array_item(array: &Array) -> Result<Self>

Access the value of a scalar array. Returns Err if the array is not scalar.

fn array_data(array: &Array) -> *const Self

Access the raw data of an array.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
