Can one of the admins verify this patch? |

The PR was rebased onto master and it compiles and passes the tests locally. |

Great, thanks a lot! I'll merge it when the tests passed. |

This is using the last size_t bytes of the object ID as a hash of the unique ID? Why not the following?
return *reinterpret_cast<const size_t *>(unique_id.id)

I think the intention was that std::hash<UniqueId>() shouldn't return the same value for consecutive IDs, which I believe Philipp said was occurring somewhere. But actually, if unique_id.id is treated as a little-endian integer and then incremented, getting the last bytes in this way would cause the hash of consecutive IDs to usually be the same.

I think @atumanov has another hash function which we should look into. I think we should merge it with Richards hash function now which is very reasonable and then we can see if we have a better alternative later.

Nice work @rshin! |
