Struct solana_gossip::ping_pong::PingCache [−][src]
pub struct PingCache { /* fields omitted */ }
Expand description
Maintains records of remote nodes which have returned a valid response to a ping message, and on-the-fly ping messages pending a pong response from the remote node.
Implementations
Checks if the pong hash, pubkey and socket match a ping message sent out previously. If so records current timestamp for the remote node and returns true. Note: Does not verify the signature.
Returns true if the remote node has responded to a ping message. Removes expired pong messages. In order to extend verifications before expiration, if the pong message is not too recent, and the node has not been pinged recently, calls the given function to generates a new ping message, records current timestamp and hash of ping token, and returns the ping message. Caller should verify if the socket address is valid. (e.g. by using ContactInfo::is_valid_address).
Only for tests and simulations.
