Enum libp2p_kad::KademliaCaching

pub enum KademliaCaching {
    Disabled,
    Enabled {
        max_peers: u16,
    },
}

The configuration for Kademlia “write-back” caching after successful lookups via Kademlia::get_record.

Variants

Disabled

Caching is disabled and the peers closest to records being looked up that do not return a record are not tracked, i.e. GetRecordOk::cache_candidates is always empty.

Enabled

Up to max_peers peers not returning a record that are closest to the key being looked up are tracked and returned in GetRecordOk::cache_candidates. Furthermore, if Kademlia::get_record is used with a quorum of 1, the found record is automatically sent to (i.e. cached at) these peers. For lookups with a quorum > 1, the write-back operation must be performed explicitly, if desired and after choosing a record from the results, via Kademlia::put_record_to.

Fields of Enabled

max_peers: u16
