Struct vapcore_network_devp2p::NetworkContext

pub struct NetworkContext<'s> { /* fields omitted */ }

IO access point. This is passed to all IO handlers and provides an interface to the IO subsystem.

Trait Implementations

impl<'s> NetworkContext for NetworkContext<'s>

fn send(
    &self,
    peer: PeerId,
    packet_id: PacketId,
    data: Vec<u8>
) -> Result<(), Error>

Send a packet over the network to another peer.

fn send_protocol(
    &self,
    protocol: ProtocolId,
    peer: PeerId,
    packet_id: PacketId,
    data: Vec<u8>
) -> Result<(), Error>

Send a packet over the network to another peer using specified protocol.

fn respond(&self, packet_id: PacketId, data: Vec<u8>) -> Result<(), Error>

Respond to a current network message. Panics if no there is no packet in the context. If the session is expired returns nothing.

fn disable_peer(&self, peer: PeerId)

Disconnect a peer and prevent it from connecting again.

fn disconnect_peer(&self, peer: PeerId)

Disconnect peer. Reconnect can be attempted later.

fn is_expired(&self) -> bool

Check if the session is still active.

fn register_timer(
    &self,
    token: TimerToken,
    delay: Duration
) -> Result<(), Error>

Register a new IO timer. ‘IoHandler::timeout’ will be called with the token.

fn peer_client_version(&self, peer: PeerId) -> ClientVersion

Returns peer identification string

fn session_info(&self, peer: PeerId) -> Option<SessionInfo>

Returns information on p2p session

fn protocol_version(&self, protocol: ProtocolId, peer: PeerId) -> Option<u8>

Returns max version for a given protocol.

fn subprotocol_name(&self) -> ProtocolId

Returns this object’s subprotocol name.

fn is_reserved_peer(&self, peer: PeerId) -> bool

Returns whether the given peer ID is a reserved peer.

fn payload_soft_limit(&self) -> usize

Returns the size the payload shouldn’t exceed
