pub struct NetworkService<B: BlockT + 'static, H: ExHashT> { /* private fields */ }
Expand description

Substrate network service. Handles network IO and manages connectivity.

Implementations

Get network state.

Note: Use this only for debugging. This API is unstable. There are warnings literally everywhere about this. Please don’t use this function to retrieve actual information.

Returns an error if the NetworkWorker is no longer running.

Trait Implementations

Request a justification for the given block from the network.

On success, the justification will be passed to the import queue that was part at initialization as part of the configuration.

Clear all pending justification requests.
Make sure an important block is propagated to peers. Read more
Inform the network service about new best imported block.

Start getting a value from the DHT.

This will generate either a ValueFound or a ValueNotFound event and pass it as an item on the NetworkWorker stream.

Start putting a value in the DHT.

This will generate either a ValuePut or a ValuePutFailed event and pass it as an item on the NetworkWorker stream.

Returns a stream containing the events that happen on the network. Read more
Appends a notification to the buffer of pending outgoing notifications with the given peer. Has no effect if the notifications channel with this protocol name is not open. Read more
Obtains a NotificationSender for a connected peer, if it exists. Read more
Set authorized peers. Read more
Set authorized_only flag. Read more
Adds an address known to a node.
Report a given peer as either beneficial (+) or costly (-) according to the given scalar. Read more
Disconnect from a node as soon as possible. Read more
Connect to unreserved peers and allow unreserved peers to connect for syncing purposes.
Disconnect from unreserved peers and deny new unreserved peers to connect for syncing purposes. Read more
Adds a PeerId and its Multiaddr as reserved. Read more
Removes a PeerId from the list of reserved peers.
Sets the reserved set of a protocol to the given set of peers. Read more

Remove peers from a peer set. Read more
Returns the number of peers in the sync peer set we’re connected to.
Sends a single targeted request to a specific peer. On success, returns the response of the peer. Read more
Variation of request which starts a request whose response is delivered on a provided channel. Read more
Signs the message with the KeyPair that defines the local PeerId.

Returns the local external addresses.

Returns the local Peer ID.

High-level network status information. Read more

Configure an explicit fork sync request. Note that this function should not be used for recent blocks. Sync should be able to download all the recent forks normally. set_sync_fork_request should only be used if external code detects that there’s a stale fork missing. Passing empty peers set effectively removes the sync request.

Whether the synchronization service is undergoing major sync. Returns true if so. Read more
Whether the synchronization service is offline. Returns true if so. Read more
