Module zebra_network::constants

Definitions of Zebra network constants, including:

• network protocol versions,
• network protocol user agents,

Modules

  Magic numbers used to identify different Zcash networks.

Structs

• INITIAL_MIN_NETWORK_PROTOCOL_VERSION
  The minimum network protocol version accepted by this crate for each network, represented as a network upgrade.
• PORT_IN_USE_ERROR
  OS-specific error when the port attempting to be opened is already in use.

Constants

• ADDR_RESPONSE_LIMIT_DENOMINATOR
  The fraction of addresses Zebra sends in response to a Peers request.

  The default peer address crawler interval.
• DEFAULT_MAX_CONNS_PER_IP
  The default maximum number of peer connections Zebra will keep for a given IP address before it drops any additional peer connections with that IP.
• DEFAULT_PEERSET_INITIAL_TARGET_SIZE
  The default peerset target size.
• DNS_LOOKUP_TIMEOUT
  The timeout for DNS lookups.
• EWMA_DECAY_TIME_NANOS
  The decay time for the EWMA response time metric used for load balancing.
• EWMA_DEFAULT_RTT
  The default RTT estimate for peer responses.
• GET_ADDR_FANOUT
  The number of GetAddr requests sent when crawling for new peers.
• HANDSHAKE_TIMEOUT
  The timeout for connections and handshakes when connecting to new peers.
• HEARTBEAT_INTERVAL
  Regular interval for sending keepalive Ping messages to each connected peer.
• INBOUND_PEER_LIMIT_MULTIPLIER
  A multiplier used to calculate the inbound connection limit for the peer set,
• INVENTORY_ROTATION_INTERVAL
  Zebra rotates its peer inventory registry every time this interval elapses.
• MAX_ADDRS_IN_ADDRESS_BOOK
  The maximum number of addresses Zebra will keep in its address book.
• MAX_ADDRS_IN_MESSAGE
  The maximum number of addresses allowed in an addr or addrv2 message.
• MAX_OVERLOAD_DROP_PROBABILITY
  The maximum probability of dropping a peer connection when it receives an Overloaded error.
• MAX_PEER_ACTIVE_FOR_GOSSIP

• MAX_PEER_DISK_CACHE_SIZE
  The maximum number of addresses in the peer disk cache.
• MAX_RECENT_PEER_AGE
  The maximum duration since a peer was last seen to consider reconnecting to it.
• MIN_INBOUND_PEER_CONNECTION_INTERVAL
  The minimum time between successful inbound peer connections, implemented by peer_set::initialize::accept_inbound_connections.
• MIN_INBOUND_PEER_FAILED_CONNECTION_INTERVAL
  The minimum time between failed inbound peer connections, implemented by peer_set::initialize::accept_inbound_connections.
• MIN_OUTBOUND_PEER_CONNECTION_INTERVAL
  The minimum time between outbound peer connections, implemented by CandidateSet::next.
• MIN_OVERLOAD_DROP_PROBABILITY
  The minimum probability of dropping a peer connection when it receives an Overloaded error.
• MIN_PEER_GET_ADDR_INTERVAL
  The minimum time between successive calls to CandidateSet::update.
• MIN_PEER_RECONNECTION_DELAY
  We expect to receive a message from a live peer at least once in this time duration.
• MIN_PEER_SET_LOG_INTERVAL
  The minimum interval between logging peer set status updates.
• NANOS_PER_SECOND 🔒
  The number of nanoseconds in one second.
• OUTBOUND_PEER_LIMIT_MULTIPLIER
  A multiplier used to calculate the outbound connection limit for the peer set,
• OVERLOAD_PROTECTION_INTERVAL
  The duration it takes for the drop probability of an overloaded connection to reach MIN_OVERLOAD_DROP_PROBABILITY.
• PEERSET_BUFFER_SIZE
  The buffer size for the peer set.
• PEER_ADDR_RESPONSE_LIMIT
  The maximum number of peers we will add to the address book after each getaddr request.

• REQUEST_TIMEOUT
  The timeout for sending a message to a remote peer, and receiving a response from a remote peer.
• TIMESTAMP_TRUNCATION_SECONDS
  Truncate timestamps in outbound address messages to this time interval.
