Trait imageproc::integral_image::ArrayData

pub trait ArrayData {
    type DataType;

    // Required methods
    fn data(&self) -> Self::DataType;
    fn add(lhs: Self::DataType, other: Self::DataType) -> Self::DataType;
    fn sub(lhs: Self::DataType, other: Self::DataType) -> Self::DataType;
}

Hack to get around lack of const generics. See comment on sum_image_pixels.

Required Associated Types

type DataType

The type of the data for this array. e.g. [T; 1] for Luma, [T; 3] for Rgb.

Required Methods

fn data(&self) -> Self::DataType

Get the data from this pixel as a constant length array.

fn add(lhs: Self::DataType, other: Self::DataType) -> Self::DataType

Add the elements of two data arrays elementwise.

fn sub(lhs: Self::DataType, other: Self::DataType) -> Self::DataType

Subtract the elements of two data arrays elementwise.

Object Safety

This trait is not object safe.
