Struct ratatu_image::FixedImage

pub struct FixedImage<'a> { /* private fields */ }

Fixed size image widget that uses FixedBackend.

The widget does not react to area resizes, and is not even guaranteed to not overdraw. Its advantage is that the FixedBackend it uses needs only one initial resize.

struct App {
    image_static: Box<dyn FixedBackend>,
}
fn ui<B: Backend>(f: &mut Frame<B>, app: &mut App) {
    let image = FixedImage::new(app.image_static.as_ref());
    f.render_widget(image, f.size());
}
