Struct Network

Source 
pub struct Network<T> { /* private fields */ }
Expand description

Running peer-to-peer node.

The primary feature of the Network is the ability to subscribe to one or more topics and exchange messages over those topics with remote peers. Replication can be conducted exclusively in “live-mode” or may include the synchronisation of past state, thereby ensuring eventual consistency among all peers for a given topic. Replication and discovery strategies are defined in the NetworkBuilder.

In addition to topic subscription, Network offers a way to access information about the local network such as the node ID and direct addresses. It also provides a convenient means to add the address of a remote peer and to query the addresses of all known peers.

Implementations§

Source§

impl<T> Network<T>
where T: TopicQuery + TopicId + 'static,

Source

pub async fn add_peer(&self, node_addr: NodeAddr) -> Result<()>

Adds a peer to the address book.

Source

pub async fn known_peers(&self) -> Result<Vec<NodeAddr>>

Returns the addresses of all known peers.

Source

pub async fn direct_addresses(&self) -> Option<Vec<SocketAddr>>

Returns the direct addresses of this node.

Source

pub fn endpoint(&self) -> &Endpoint

Returns a handle to the network endpoint.

The Endpoint exposes low-level networking functionality such as the ability to connect to specific peers, accept connections, query local socket addresses and more.

This level of control is unlikely to be required in most cases but has been exposed for the convenience of advanced users.

Source

pub fn node_id(&self) -> PublicKey

Returns the public key of the node.

Source

pub async fn shutdown(self) -> Result<()>

Terminates all internal tasks and shuts down the node.

Source

pub async fn subscribe( &self, topic: T, ) -> Result<(Sender<ToNetwork>, Receiver<FromNetwork>, Receiver<()>)>

Subscribes to a topic and returns a bi-directional stream that can be read from and written to, along with a oneshot receiver to be informed when the gossip overlay has been joined.
