preferredServers :: StorageIndex -> Map Text StorageServerAnnouncement -> [(StorageServerID, StorageServerAnnouncement)] Source #

Find the preferred order of servers for an object with the given index.

This is like allmydata.storage_client.StorageFarmBroker.get_servers_for_psi

storageServerPermutationSeed :: StorageServerID -> StorageServerAnnouncement -> ByteString Source #

Compute a sort key for a storage server given its identifier and storage service announcement.

This is like pieces of allmydata.storage_client._parse_announcement
