    frontend: &(dyn AnyFrontend + 'static)
)

pub fn set_data<D>(&self, new_data: D) where
    D: FrontendImage, 

Sets the internal frontend data for this image. Should not be used outside of developing a frontend.

pub fn map_data<R, F>(&self, callback: F) -> R where
    F: FnOnce(Option<&mut (dyn FrontendImage + 'static)>) -> R, 

Maps the frontend data into callback returning the result of the function. This is generally only useful when developing a frontend.
