}Expand description
The peer address that we are handshaking with.
Typically, we can rely on outbound addresses, but inbound addresses don’t give us enough information to reconnect to that peer.
Variants§
OutboundDirect
The address we used to make a direct outbound connection.
In an honest network, a Zcash peer is listening on this exact address and port.
Fields
§
addr: PeerSocketAddrThe connected outbound remote address and port.
InboundDirect
The address we received from the OS, when a remote peer directly connected to our Zcash listener port.
In an honest network, a Zcash peer might be listening on this address, if its outbound address is the same as its listener address. But the port is an ephemeral outbound TCP port, not a listener port.
Fields
§
addr: PeerSocketAddrThe connected inbound remote address and ephemeral port.
The IP address might be the address of a Zcash peer, but the port is an ephemeral port.
OutboundProxy
The proxy address we used to make an outbound connection.
The proxy address can be used by many connections, but our own ephemeral outbound address and port can be used as an identifier for the duration of this connection.
Fields
§
proxy_addr: SocketAddrThe remote address and port of the proxy.
§
transient_local_addr: SocketAddrThe local address and transient port we used to connect to the proxy.
InboundProxy
The address we received from the OS, when a remote peer connected via an inbound proxy.
The proxy’s ephemeral outbound address can be used as an identifier for the duration of this connection.
Fields
§
transient_addr: SocketAddrThe local address and transient port we used to connect to the proxy.
Isolated
An isolated connection, where we deliberately don’t have any connection metadata.
Implementations§
source§impl ConnectedAddr
impl ConnectedAddr
sourcepub fn new_outbound_direct(addr: PeerSocketAddr) -> ConnectedAddr
pub fn new_outbound_direct(addr: PeerSocketAddr) -> ConnectedAddr
Returns a new outbound directly connected addr.
sourcepub fn new_inbound_direct(addr: PeerSocketAddr) -> ConnectedAddr
pub fn new_inbound_direct(addr: PeerSocketAddr) -> ConnectedAddr
Returns a new inbound directly connected addr.
sourcepub fn new_outbound_proxy(
proxy: SocketAddr,
local_addr: SocketAddr,
) -> ConnectedAddr
pub fn new_outbound_proxy( proxy: SocketAddr, local_addr: SocketAddr, ) -> ConnectedAddr
Returns a new outbound connected addr via proxy.
local_addr is the ephemeral local address of the connection.
sourcepub fn new_inbound_proxy(proxy: SocketAddr) -> ConnectedAddr
pub fn new_inbound_proxy(proxy: SocketAddr) -> ConnectedAddr
Returns a new inbound connected addr from proxy.
sourcepub fn new_isolated() -> ConnectedAddr
pub fn new_isolated() -> ConnectedAddr
Returns a new isolated connected addr, with no metadata.
sourcepub fn get_address_book_addr(&self) -> Option<PeerSocketAddr>
pub fn get_address_book_addr(&self) -> Option<PeerSocketAddr>
Returns a PeerSocketAddr that can be used to track this connection in the
AddressBook.
None for inbound connections, proxy connections, and isolated
connections.
§Correctness
This address can be used for reconnection attempts, or as a permanent identifier.
§Security
This address must not depend on the canonical address from the Version
message. Otherwise, malicious peers could interfere with other peers
AddressBook state.
TODO: remove the get_ from these methods (Rust style avoids get prefixes)
sourcepub fn get_transient_addr(&self) -> Option<PeerSocketAddr>
pub fn get_transient_addr(&self) -> Option<PeerSocketAddr>
Returns a PeerSocketAddr that can be used to temporarily identify a
connection.
Isolated connections must not change Zebra’s peer set or address book state, so they do not have an identifier.
§Correctness
The returned address is only valid while the original connection is
open. It must not be used in the AddressBook, for outbound connection
attempts, or as a permanent identifier.
§Security
This address must not depend on the canonical address from the Version
message. Otherwise, malicious peers could interfere with other peers’
PeerSet state.
sourcepub fn get_transient_addr_label(&self) -> String
pub fn get_transient_addr_label(&self) -> String
Returns the metrics label for this connection’s address.
sourcepub fn get_short_kind_label(&self) -> &'static str
pub fn get_short_kind_label(&self) -> &'static str
Returns a short label for the kind of connection.
sourcepub fn get_alternate_addrs(
&self,
canonical_remote: PeerSocketAddr,
) -> impl Iterator<Item = PeerSocketAddr>
pub fn get_alternate_addrs( &self, canonical_remote: PeerSocketAddr, ) -> impl Iterator<Item = PeerSocketAddr>
Returns a list of alternate remote peer addresses, which can be used for reconnection attempts.
Uses the connected address, and the remote canonical address.
Skips duplicates. If this is an outbound connection, also skips the remote address that we’re currently connected to.
