Enum ImageState 

pub enum ImageState<'a> {
    Ready,
    Loading,
    Failed(&'a str),
}

Where an Image’s pixels are: here, on their way, or never coming.

Three and not 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

Ready

The pixels are here.

Loading

In flight, or being decoded; a later frame will have them. Image::network reports this while it fetches, and Image::memory while a large picture decodes.

Failed(&'a str)

They will not arrive, and this is why.
