Variants§

§

Insert

Hosts that are currently being inserting into the hostlist.

§

Refine

Hosts that are migrating from the greylist to the whitelist or being removed from the greylist, as defined in refinery.rs.

§

Connect

Hosts that are being connected to in Outbound and Manual Session.

§

Suspend

Hosts that we have just failed to connect to. Marking a host as Suspend effectively sends this host to refinery, since Suspend-> Refine is an acceptable state transition. Being marked as Suspend does not increase a host’s probability of being refined, since the refinery selects its subjects randomly (with the caveat that we cannot refine nodes marked as Connect, Connected, Insert or Move). It does however mean this host cannot be connected to unless it passes through the refinery successfully.

§

Connected(ChannelPtr)

Hosts that have been successfully connected to.

§

Move

Host that are moving between hostlists, implemented in store::move_host().

§

Free(u64)

Free up a peer for any future operation.
