struct PeerDiscovery {
process: StoppableTaskPtr,
wakeup_self: CondVar,
session: Weak<OutboundSession>,
}
Expand description
Main PeerDiscovery process that loops through connected peers
and sends out a GetAddrs
when it is active. If there are no
connected peers after two attempts, connect to our seed nodes
and perform SeedSyncSession
.

Activate peer discovery if not active already. For the first two
attempts, this will loop through all connected P2P peers and send
out a GetAddrs
message to request more peers. Other parts of the
P2P stack will then handle the incoming addresses and place them in
the hosts list.
On the third attempt, and if we still haven’t made any connections,
this function will then call p2p.seed()
which triggers a
SeedSyncSession
that will connect to configured seeds and request
peers from them.
This function will also sleep outbound_peer_discovery_attempt_time
seconds after broadcasting in order to let the P2P stack receive and
work through the addresses it is expecting.

'life0: 'async_trait,
Blocks execution until we receive a notification from notify().
wakeup_self.wait()
resets the condition variable (CondVar
) and waits
for a call from notify()
. Returns true
if the function completed
instantly (i.e. no wait occured). Returns false otherwise.
Source§fn notify(&self)
fn notify(&self)
Wakeup peer discovery by sending a notification to wakeup_self
.
Uses the underlying CondVar
method notify()
. Subsequent calls
to this do nothing until wait()
is called.
