Trait show_image::ImageData

pub trait ImageData {
    fn data(self) -> Box<[u8]>;
    fn info(&self) -> Result<ImageInfo, String>;

    fn into_image_tuple(self) -> Result<(Box<[u8]>, ImageInfo), String>
    where
        Self: Sized,
    { ... }
}

Allows a type to be displayed as an image.

This trait is implemented for tuples of (Data, ImageInfo) if Data can be converted into a Box<[u8]>, and for &(Data, ImageInfo) if Data is AsRef<[u8]>. Amongst others, that includes &[u8], Box<[u8]>, Vec<u8>.

Implementations for types from third-party libraries can be enabled using feature flags.

Required methods

fn data(self) -> Box<[u8]>

Get the image data as boxed slice.

This function takes self by value to prevent copying if possible. If the data can not be moved into a box, consider implementing the trait for references.

fn info(&self) -> Result<ImageInfo, String>

Get the ImageInfo describing the binary data.

This function may fail at runtime if the data can not be described properly.
