pub struct PeerManagerRequestSender { /* private fields */ }
Expand description

Convenience wrapper which makes it easy to issue communication requests and await the responses from PeerManager.

Implementations§

source§

impl PeerManagerRequestSender

source

pub fn new(inner: Sender<(PeerId, ProtocolId), PeerManagerRequest>) -> Self

Construct a new PeerManagerRequestSender with a raw channel::Sender

source

pub fn send_to( &mut self, peer_id: PeerId, protocol_id: ProtocolId, mdata: Bytes ) -> Result<(), PeerManagerError>

Send a fire-and-forget direct-send message to remote peer.

The function returns when the message has been enqueued on the network actor’s event queue. It therefore makes no reliable delivery guarantees. An error is returned if the event queue is unexpectedly shutdown.

source

pub fn send_to_many( &mut self, recipients: impl Iterator<Item = PeerId>, protocol_id: ProtocolId, mdata: Bytes ) -> Result<(), PeerManagerError>

Send the same message to many recipients using the direct-send protocol.

This method is an optimization so that we can avoid serializing and copying the same message many times when we want to sent a single message to many peers. Note that the Bytes the messages is serialized into is a ref-counted byte buffer, so we can avoid excess copies as all direct-sends will share the same underlying byte buffer.

The function returns when all send requests have been enqueued on the network actor’s event queue. It therefore makes no reliable delivery guarantees. An error is returned if the event queue is unexpectedly shutdown.

source

pub async fn send_rpc( &mut self, peer_id: PeerId, protocol_id: ProtocolId, req: Bytes, timeout: Duration ) -> Result<Bytes, RpcError>

Sends a unary RPC to a remote peer and waits to either receive a response or times out.
