Struct arti_client::TorAddr
source · pub struct TorAddr { /* private fields */ }
Expand description
An address object that you can connect to over the Tor network.
When you’re making a connection with Tor, you shouldn’t do your DNS lookups locally: that would leak your target address to your DNS server. Instead, it’s better to use a combination of a hostname and a port directly.
The preferred way to create a TorAddr
is via the IntoTorAddr
trait,
using a hostname and a port (or a string containing a hostname and a
port). It’s also okay to use an IP and Port there, but only if they come
from some source other than a local DNS lookup.
In order to discourage local hostname lookups, the functions that
construct a TorAddr
from IpAddr
, SocketAddr
, and so
forth are labeled as “dangerous”.
Examples
Making a TorAddr
from various “safe” sources:
use arti_client::IntoTorAddr;
let example_from_tuple = ("example.com", 80).into_tor_addr()?;
let example_from_string = "example.com:80".into_tor_addr()?;
assert_eq!(example_from_tuple, example_from_string);
Making a TorAddr
from an IP address and port:
Warning: This example is only safe because we’re not doing a DNS lookup; rather, the intent is to connect to a hardcoded IP address. If you’re using
DangerouslyIntoTorAddr
, pay careful attention to where your IP addresses are coming from, and whether there’s a risk of information leakage.
use arti_client::DangerouslyIntoTorAddr;
use std::net::{IpAddr, SocketAddr};
let quad_one_dns: SocketAddr = "1.1.1.1:53".parse()?;
let addr_from_socketaddr = quad_one_dns.into_tor_addr_dangerously()?;
let quad_one_ip: IpAddr = "1.1.1.1".parse()?;
let addr_from_tuple = (quad_one_ip, 53).into_tor_addr_dangerously()?;
assert_eq!(addr_from_socketaddr, addr_from_tuple);
Implementations§
source§impl TorAddr
impl TorAddr
sourcepub fn from<A: IntoTorAddr>(addr: A) -> Result<Self, TorAddrError>
pub fn from<A: IntoTorAddr>(addr: A) -> Result<Self, TorAddrError>
Construct a TorAddr
from any object that implements
IntoTorAddr
.
sourcepub fn dangerously_from<A: DangerouslyIntoTorAddr>(
addr: A
) -> Result<Self, TorAddrError>
pub fn dangerously_from<A: DangerouslyIntoTorAddr>( addr: A ) -> Result<Self, TorAddrError>
Construct a TorAddr
from any object that implements
DangerouslyIntoTorAddr
.
See DangerouslyIntoTorAddr
for an explanation of why the
style of programming supported by this function is dangerous
to use.
sourcepub fn is_ip_address(&self) -> bool
pub fn is_ip_address(&self) -> bool
Return true if this is an IP address (rather than a hostname).
