So far I've been trying to get an example working with using `from_hash`. The complication is that `from_hash` only can have a look at the hash value, and not have an offset (to compare the collissions). I think that using the rawtable API https://docs.rs/hashbrown/0.11.2/hashbrown/raw/struct.RawTable.html might help here as we can store elements of type `(u64, usize)` as a key and avoiding the raw entry interface. The "identity" ha her in this case can just return the first value of the tuple. -- This is an automated message from the Apache Git Service.
