Type Alias BlobFetchError 

pub type BlobFetchError = Box<dyn Error + Send + Sync>;

The error a digest-only entry’s fetch closure failed with. Opaque on purpose — the caller’s storage layer (a DB, a filesystem, an object store) is not this crate’s concern, only that the failure is reported rather than swallowed.
