Enum ProviderFetch 

Source 
pub enum ProviderFetch<W: MessageWriter<Error = Error>, R: MessageReader<Error = Error>> {
    Direct(Box<Download<R>>),
    Provider(Box<ProviderDownload<W, R>>),
}
Expand description

The issuer may explicitly select ordinary direct source delivery when a preferred provider transfer cannot be offered. Only the admitted Ready decides the branch; an arbitrary stream error never triggers a retry.
