Module tasks 

Functions

add_node_task

Add a node to the DHT buckets. If the bucket is already full, we ping the least recently seen node in the bucket: if successful it becomes the most recently seen node, if the ping fails we remove it and add the new node. crate::dht::Dht::update_node() increments a channel’s usage count (in the direct session) and triggers this task. This task decrements the usage count using crate::dht::Dht::cleanup_channel().

channel_task

Send a DHT ping request when there is a new channel, to know the node id of the new peer, Then fill the channel cache and the buckets

cleanup_channels_task

Removes entries from crate::dht::Dht::channel_cache when a channel is stopped.

dht_refinery_task

Periodically send a DHT ping to known hosts. If the ping is successful, we move the host to the whitelist (updating the last seen field).

disconnect_inbounds_task

Close inbound connections that are unused for too long.

events_task

Handle DHT events.
