Trait 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.

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.
