Trait ImageData 

pub unsafe trait ImageData: Copy + Default {
    type STORAGE: Copy;

    const TYPE: ImageType;

    // Required methods
    fn getter(    ) -> unsafe extern "C" fn(MImage, *mut mint, mint, *mut Self) -> c_int;
    fn setter() -> unsafe extern "C" fn(MImage, *mut mint, mint, Self) -> c_int;
}

Trait implemented for types that can logically be stored in an Image.

The STORAGE associated type represents the data that is physically stored in the Image buffer.

The following logical types can be used in an image:

• bool
• u8, u16
• f32, f64

Safety

This trait is already implemented for all types that can legally be stored in an Image. Implementing this trait for other types may lead to undefined behavior.

Required Associated Constants

const TYPE: ImageType

The ImageType variant represented by Self.

Required Associated Types

type STORAGE: Copy

The type of the data that is physically stored in the Image buffer.

In practice, this type is equal to Self for every logicaly type except bool, which represents a bitmapped image that logically stores a single bit of boolean data, but physically allocate one byte for each pixel/channel.

Required Methods

fn getter() -> unsafe extern "C" fn(MImage, *mut mint, mint, *mut Self) -> c_int

fn setter() -> unsafe extern "C" fn(MImage, *mut mint, mint, Self) -> c_int

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
