DefaultEngineConfig returns a default engine configuration that can and should be adjusted for different networks.

NewEngine initializes a new engine.

CrawlHandler is the default implementation for a [Handler] that can be used as the basis for crawl operations.

CrawlResult captures data that is gathered from crawling a single peer.

CrawlWriter handles the insert/upsert/update operations for a particular crawl result.

DialResult captures data that is gathered from pinging a single peer.

DialWriter handles the insert/upsert/update operations for a particular crawl result.

Engine is the integral data structure for orchestrating the communication with peers and writing the processing results to disk.

The EngineConfig object configures the core Nebula [Engine] below.

A Pool manages a set of Workers.

PriorityQueue is can take unique items and pops them according to their priority.

Result is a generic result object.

RoutingTable captures the routing table information and crawl error of a particular peer.

WriteResult must be returned by write workers.

A Driver is a data structure that provides the necessary implementations and tasks for the engine to operate.

Handler defines the interface that the engine will call every time it has received a result from any of its workers.

PeerInfo is the interface that any peer information struct must conform to.

A Worker processes tasks of type T and returns results of type R or an error.

WorkResult must be implemented by the result that a Worker which processes peers returns.
