Multiple matching links were found

`InvalidCid(InvalidCidInLink)`

Invalid Cid was matched

`UnexpectedBucketType(UnexpectedNodeType)`

Unexpected HAMT shard bucket type

`Shard(ShardError)`

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
