//! Kademlia protocol. Allows peer discovery, records store and records fetch.
//!
//! # Usage
//!
//! Usage is done in the following steps:
//!
//! - Build a `KadSystemConfig` and a `KadConnecConfig` object that contain the way you want the
//!   Kademlia protocol to behave.
//!
//! - Create a swarm that upgrades incoming connections with the `KadConnecConfig`.
//!
//! - Build a `KadSystem` from the `KadSystemConfig`. This requires passing a closure that provides
//!   the Kademlia controller of a peer.
//!
//! - You can perform queries using the `KadSystem`.
//!

// TODO: we allow dead_code for now because this library contains a lot of unused code that will
//       be useful later for record store
#![allow(dead_code)]

// # Crate organization
//
// The crate contains three levels of abstractions over the Kademlia protocol.
//
// - The first level of abstraction is in `protocol`. The API of this module lets you turn a raw
//   bytes stream (`AsyncRead + AsyncWrite`) into a `Sink + Stream` of raw but strongly-typed
//   Kademlia messages.
//
// - The second level of abstraction is in `kad_server`. Its API lets you upgrade a connection and
//   obtain a future (that must be driven to completion), plus a controller. Processing the future
//   will automatically respond to Kad requests received by the remote. The controller lets you
//   send your own requests to this remote and obtain strongly-typed responses.
//
// - The third level of abstraction is in `high_level`. This module only provides the
//   `KademliaSystem`.
