Enum polkadot_node_subsystem::messages::network_bridge_event::NetworkBridgeEvent

pub enum NetworkBridgeEvent<M> {
    PeerConnected(PeerId, ObservedRole, ProtocolVersion, Option<HashSet<Public, RandomState>>),
    PeerDisconnected(PeerId),
    NewGossipTopology(NewGossipTopology),
    PeerMessage(PeerId, M),

}

Events from network.

Variants

PeerConnected(PeerId, ObservedRole, ProtocolVersion, Option<HashSet<Public, RandomState>>)

A peer has connected.

PeerDisconnected(PeerId)

A peer has disconnected.

NewGossipTopology(NewGossipTopology)

Our neighbors in the new gossip topology for the session. We’re not necessarily connected to all of them.

This message is issued only on the validation peer set.

Note, that the distribution subsystems need to handle the last view update of the newly added gossip peers manually.

PeerMessage(PeerId, M)

Peer has sent a message.

PeerViewChange(PeerId, View)

Peer’s View has changed.

OurViewChange(OurView)

Our view has changed.

Implementations

impl<M> NetworkBridgeEvent<M>

pub fn focus<'a, T>(&'a self) -> Result<NetworkBridgeEvent<T>, WrongVariant>where T: 'a + Clone + TryFrom<&'a M, Error = WrongVariant>,

Focus an overarching network-bridge event into some more specific variant.

This tries to transform M in PeerMessage to a message type specific to a subsystem. It is used to dispatch events coming from a peer set to the various subsystems that are handled within that peer set. More concretely a ValidationProtocol will be transformed for example into a BitfieldDistributionMessage in case of the BitfieldDistribution constructor.

Therefore a NetworkBridgeEvent<ValidationProtocol> will become for example a NetworkBridgeEvent<BitfieldDistributionMessage>, with the more specific message type BitfieldDistributionMessage.

This acts as a call to clone, except in the case where the event is a message event, in which case the clone can be expensive and it only clones if the message type can be focused.

Trait Implementations

impl<M> Clone for NetworkBridgeEvent<M>where M: Clone,

fn clone(&self) -> NetworkBridgeEvent<M>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M> Debug for NetworkBridgeEvent<M>where M: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<NetworkBridgeEvent<Versioned<ApprovalDistributionMessage>>> for ApprovalDistributionMessage

fn from( original: NetworkBridgeEvent<Versioned<ApprovalDistributionMessage>> ) -> ApprovalDistributionMessage

Converts to this type from the input type.

impl From<NetworkBridgeEvent<Versioned<BitfieldDistributionMessage>>> for BitfieldDistributionMessage

fn from( original: NetworkBridgeEvent<Versioned<BitfieldDistributionMessage>> ) -> BitfieldDistributionMessage

Converts to this type from the input type.

impl From<NetworkBridgeEvent<Versioned<CollatorProtocolMessage>>> for CollatorProtocolMessage

fn from( original: NetworkBridgeEvent<Versioned<CollatorProtocolMessage>> ) -> CollatorProtocolMessage

Converts to this type from the input type.

impl From<NetworkBridgeEvent<Versioned<GossipSupportNetworkMessage>>> for GossipSupportMessage

fn from( original: NetworkBridgeEvent<Versioned<GossipSupportNetworkMessage>> ) -> GossipSupportMessage

Converts to this type from the input type.

impl From<NetworkBridgeEvent<Versioned<StatementDistributionMessage>>> for StatementDistributionMessage

fn from( original: NetworkBridgeEvent<Versioned<StatementDistributionMessage>> ) -> StatementDistributionMessage

Converts to this type from the input type.

impl<M> PartialEq<NetworkBridgeEvent<M>> for NetworkBridgeEvent<M>where M: PartialEq<M>,

fn eq(&self, other: &NetworkBridgeEvent<M>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
