Enum AssetState 

pub enum AssetState<A> {
    Unloaded,
    Loading,
    Ready(Arc<A>),
    Failed(Arc<Error>),
}

Observable shared lifecycle with its sticky result; observing never starts loading.

Variants

Unloaded

No read or decode has begun.

Loading

One caller is reading/decoding; others join the same result.

Ready(Arc<A>)

An immutable decoded resource is available.

Failed(Arc<Error>)

A sticky diagnostic is available; failures are not retried implicitly.
