Fields

events: VecDeque<ServiceEvent>

Queue of events produced by the session service.

config: Discv5Config

Configuration for the discv5 service.

enr: Enr<CombinedKey>

The local ENR.

key: CombinedKey

The key to sign the ENR and set up encrypted communication with peers.

pending_requests: TimedRequests

Pending raw requests. A list of raw messages we are awaiting a response from the remote. These are indexed by SocketAddr as WHOAREYOU messages do not return a source node id to match against.

pending_messages: HashMap<NodeId, Vec<ProtocolMessage>>

Pending messages. Messages awaiting to be sent, once a handshake has been established.

sessions: TimedSessions

Sessions that have been created for each node id. These can be established or awaiting response from remote nodes.

transport: Transport

The discovery v5 UDP service.

Implementations

`impl Service`[src]

`pub(crate) fn new( enr: Enr<CombinedKey>, key: CombinedKey, listen_socket: SocketAddr, config: Discv5Config ) -> Result<Self, Discv5Error>`[src]

A new Session service which instantiates the UDP socket.

`pub(crate) fn enr(&self) -> &Enr<CombinedKey>`[src]

The local ENR of the service.

`pub(crate) fn enr_insert( &mut self, key: &str, value: Vec<u8> ) -> Result<Option<Vec<u8>>, EnrError>`[src]

Generic function to modify a field in the local ENR.

`pub(crate) fn update_local_enr_socket( &mut self, socket: SocketAddr, is_tcp: bool ) -> Result<(), EnrError>`[src]

Updates the local ENR SocketAddr for either the TCP or UDP port.

`pub(crate) fn update_enr(&mut self, enr: Enr<CombinedKey>)`[src]

Updates a session if a new ENR or an updated ENR is discovered.

`pub(crate) fn send_request( &mut self, dst_enr: &Enr<CombinedKey>, message: ProtocolMessage ) -> Result<(), Discv5Error>`[src]

Sends a ProtocolMessage request to a known ENR. It is possible to send requests to IP addresses not related to the ENR.

`pub(crate) fn send_request_unknown_enr( &mut self, dst: SocketAddr, dst_id: &NodeId, message: ProtocolMessage ) -> Result<(), Discv5Error>`[src]

Similar to send_request but for requests which an ENR may be unknown. A session is therefore assumed to be valid.

`pub(crate) fn send_response( &mut self, dst: SocketAddr, dst_id: &NodeId, message: ProtocolMessage ) -> Result<(), Discv5Error>`[src]

Sends an RPC Response. This differs from send request as responses do not require a known ENR to send messages and session's should already be established.

`pub(crate) fn send_whoareyou( &mut self, dst: SocketAddr, node_id: &NodeId, enr_seq: u64, remote_enr: Option<Enr<CombinedKey>>, auth_tag: AuthTag )`[src]

This is called in response to a ServiceMessage::WhoAreYou event. The protocol finds the highest known ENR then calls this function to send a WHOAREYOU packet.

`fn src_id(&self, tag: &Tag) -> NodeId`[src]

Calculates the src NodeId given a tag.

`fn tag(&self, dst_id: &NodeId) -> Tag`[src]

Calculates the tag given a NodeId.

`fn handle_whoareyou( &mut self, src: SocketAddr, token: AuthTag, id_nonce: Nonce, enr_seq: u64 ) -> Result<(), ()>`[src]

Handles a WHOAREYOU packet that was received from the network.

`fn handle_auth_message( &mut self, src: SocketAddr, tag: Tag, auth_header: AuthHeader, message: &[u8] ) -> Result<(), ()>`[src]

Handle a message that contains an authentication header.

`fn handle_message( &mut self, src: SocketAddr, src_id: NodeId, auth_tag: AuthTag, message: &[u8], tag: Tag ) -> Result<(), ()>`[src]

Handle a standard message that does not contain an authentication header.

`fn flush_messages(&mut self, dst: SocketAddr, dst_id: &NodeId) -> Result<(), ()>`[src]

Encrypts and sends any messages that were waiting for a session to be established.

`fn process_request( &mut self, dst: SocketAddr, dst_id: NodeId, packet: Packet, message: Option<ProtocolMessage> )`[src]

Wrapper around transport.send() that adds all sent messages to the pending_requests. This builds a request adds a timeout and sends the request.

`fn check_timeouts(&mut self, cx: &mut Context)`[src]

The heartbeat which checks for timeouts and reports back failed RPC requests/sessions.
