Struct NetworkHandle

pub struct NetworkHandle<N = EthNetworkPrimitives>
where
    N: NetworkPrimitives,
{ /* private fields */ }

A shareable network frontend. Used to interact with the network.

See also NetworkManager.

Implementations

impl<N> NetworkHandle<N>

where N: NetworkPrimitives,

pub fn peer_id(&self) -> &FixedBytes<64>

Returns the [PeerId] used in the network.

pub fn mode(&self) -> &NetworkMode

Returns the mode of the network, either pow, or pos

pub fn update_status(&self, head: Head)

Update the status of the node.

pub fn announce_block( &self, block: NewBlock<<N as NetworkPrimitives>::Block>, hash: FixedBytes<32>, )

Announce a block over devp2p

Caution: in PoS this is a noop because new blocks are no longer announced over devp2p. Instead they are sent to the node by CL and can be requested over devp2p. Broadcasting new blocks is considered a protocol violation.

pub fn send_request(&self, peer_id: FixedBytes<64>, request: PeerRequest<N>)

Sends a PeerRequest to the given peer’s session.

pub fn send_transactions_hashes( &self, peer_id: FixedBytes<64>, msg: NewPooledTransactionHashes, )

Send transactions hashes to the peer.

pub fn send_transactions( &self, peer_id: FixedBytes<64>, msg: Vec<Arc<<N as NetworkPrimitives>::BroadcastedTransaction>>, )

Send full transactions to the peer

pub async fn transactions_handle(&self) -> Option<TransactionsHandle<N>>

Send message to get the TransactionsHandle.

Returns None if no transaction task is installed.

pub async fn shutdown(&self) -> Result<(), RecvError>

Send message to gracefully shutdown node.

This will disconnect all active and pending sessions and prevent new connections to be established.

pub fn set_network_active(&self)

Set network connection state to Active.

New outbound connections will be established if there’s capacity.

pub fn set_network_hibernate(&self)

Set network connection state to Hibernate.

No new outbound connections will be established.

pub fn tx_gossip_disabled(&self) -> bool

Whether tx gossip is disabled

pub fn secret_key(&self) -> &SecretKey

Returns the secret key used for authenticating sessions.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
