A ClosestNodesIter iterates nodes in order of ascending distance from a key.

EventPoolAddQuery is an event that attempts to add a new query that finds closer nodes to a target key.

EventPoolAddQuery is an event that attempts to add a new query that sends a message.

EventPoolNodeFailure notifies a [Pool] that an attempt to contact a node has failed.

EventPoolNodeResponse notifies a [Pool] that an attempt to contact a node has received a successful response.

EventPoolPoll is an event that signals the pool that it can perform housekeeping work such as time out queries.

EventPoolStopQuery notifies a [Pool] to stop a query.

EventQueryMessageResponse notifies a query to stop all work and enter the finished state.

A SequentialIter iterates nodes in the order they were added to the iterator.

StateNodeFailed indicates that the attempt to contact the node failed.

StateNodeNotContacted indicates that the node has not been contacted yet.

StateNodeSucceeded indicates that the attempt to contact the node succeeded.

StateNodeUnresponsive indicates that the node did not respond within the configured timeout.

StateNodeWaiting indicates that a query is waiting for a response from the node.

StatePoolFindCloser indicates that a pool query wants to send a find closer nodes message to a node.

StatePoolIdle indicates that the pool is idle, i.e.

StatePoolQueryFinished indicates that a query has finished.
