Enum Fetched 

pub enum Fetched {
    Loading,
    Ready(Arc<ImageData>),
    Failed(String),
}

The image stores, for an application that loads its own pictures or sizes the cache. What is known about an image that has to be fetched before it can be shown.

Three states rather than two, because “not here yet” and “will never be here” are different answers and an interface shows them differently: one is a placeholder, the other is a message.

Variants

Loading

In flight. Ask again on a later frame.

Ready(Arc<ImageData>)

Here.

Failed(String)

It will not arrive, and this is why.
