We get an error from iroh_car::Error::Parsing with string "early eof". Possible sources that match this error all deconstruct into io::Error, but io::Error::UnexpectedEof stringifies as "unexpected end of file", not "early eof".

Possible sources:

• From<cid::Error>: cid::Error::Io(io::Error)
• From<multihash::Error>: multihash::Error { kind: Kind::Io(io::Error) }
• ld_read(): unsigned_varint::io::ReadError::Io(io::Error)
• reader.read_exact(): io:Error
• CarHeader::decode() -> DagCborCodec::decode(): dag_cbor::CborError::{Io(io::Error), Cid(cid::Error::Io(io::Error)}
