pub(super) struct SyncNetworkContext<DB> {
network_send: Sender<NetworkMessage>,
peer_manager: Arc<PeerManager>,
db: Arc<DB>,
}
Expand description
Context used in chain sync to handle network requests.
This contains the peer manager, P2P service interface, and Blockstore
required to make network requests.
Fields§
§network_send: Sender<NetworkMessage>
Channel to send network messages through P2P service
peer_manager: Arc<PeerManager>
Manages peers to send requests to and updates request stats for the respective peers.
db: Arc<DB>

DB: Blockstore,
impl<DB> SyncNetworkContext<DB>where
DB: Blockstore,
pub fn new( network_send: Sender<NetworkMessage>, peer_manager: Arc<PeerManager>, db: Arc<DB>, ) -> Self
sourcepub fn peer_manager(&self) -> &PeerManager
pub fn peer_manager(&self) -> &PeerManager
Returns a reference to the peer manager of the network context.
sourcepub async fn chain_exchange_headers(
&self,
peer_id: Option<PeerId>,
tsk: &TipsetKey,
count: NonZeroU64,
) -> Result<Vec<Arc<Tipset>>, String>
pub async fn chain_exchange_headers( &self, peer_id: Option<PeerId>, tsk: &TipsetKey, count: NonZeroU64, ) -> Result<Vec<Arc<Tipset>>, String>
Send a chain_exchange
request for only block headers (ignore
messages). If peer_id
is None
, requests will be sent to a set of
shuffled peers.
sourcepub async fn chain_exchange_messages(
&self,
peer_id: Option<PeerId>,
tipsets: &[Arc<Tipset>],
) -> Result<Vec<CompactedMessages>, String>
pub async fn chain_exchange_messages( &self, peer_id: Option<PeerId>, tipsets: &[Arc<Tipset>], ) -> Result<Vec<CompactedMessages>, String>
Send a chain_exchange
request for only messages (ignore block
headers). If peer_id
is None
, requests will be sent to a set of
shuffled peers.
sourcepub async fn chain_exchange_fts(
&self,
peer_id: Option<PeerId>,
tsk: &TipsetKey,
) -> Result<FullTipset, String>
pub async fn chain_exchange_fts( &self, peer_id: Option<PeerId>, tsk: &TipsetKey, ) -> Result<FullTipset, String>
Send a chain_exchange
request for a single full tipset (includes
messages) If peer_id
is None
, requests will be sent to a set of
shuffled peers.
sourcepub async fn bitswap_get<TMessage: DeserializeOwned>(
&self,
content: Cid,
epoch: Option<i64>,
) -> Result<TMessage, String>
pub async fn bitswap_get<TMessage: DeserializeOwned>( &self, content: Cid, epoch: Option<i64>, ) -> Result<TMessage, String>
Requests that some content with a particular Cid
get fetched over
Bitswap
if it doesn’t exist in the BlockStore
.
sourceasync fn handle_chain_exchange_request<T, F>(
&self,
peer_id: Option<PeerId>,
tsk: &TipsetKey,
request_len: NonZeroU64,
options: u64,
validate: F,
) -> Result<Vec<T>, String>
async fn handle_chain_exchange_request<T, F>( &self, peer_id: Option<PeerId>, tsk: &TipsetKey, request_len: NonZeroU64, options: u64, validate: F, ) -> Result<Vec<T>, String>
Helper function to handle the peer retrieval if no peer supplied as well
as the logging and updating of the peer info in the PeerManager
.
sourceasync fn chain_exchange_request(
peer_manager: Arc<PeerManager>,
network_send: Sender<NetworkMessage>,
peer_id: PeerId,
request: ChainExchangeRequest,
) -> Result<ChainExchangeResponse, String>
async fn chain_exchange_request( peer_manager: Arc<PeerManager>, network_send: Sender<NetworkMessage>, peer_id: PeerId, request: ChainExchangeRequest, ) -> Result<ChainExchangeResponse, String>
Send a chain_exchange
request to the network and await response.
sourcepub async fn hello_request(
&self,
peer_id: PeerId,
request: HelloRequest,
) -> Result<(PeerId, SystemTime, Option<HelloResponse>)>
pub async fn hello_request( &self, peer_id: PeerId, request: HelloRequest, ) -> Result<(PeerId, SystemTime, Option<HelloResponse>)>
Send a hello request to the network (does not immediately await response).
