Purpose of a circuit.

Describes what a circuit is intended for. Introduced in Tor version 0.2.1.6.

Example

use stem_rs::CircPurpose;

let purpose = CircPurpose::General;
println!("Circuit purpose: {}", purpose); // Prints "GENERAL"

Variants

General

General client traffic or fetching directory information.

Standard circuits used for normal Tor operations.

HsClientIntro

Client-side introduction point for a hidden service circuit.

Used when connecting to a hidden service’s introduction point.

HsClientRend

Client-side hidden service rendezvous circuit.

Used for the rendezvous connection when accessing a hidden service.

HsServiceIntro

Server-side introduction point for a hidden service circuit.

Used by hidden services to establish introduction points.

HsServiceRend

Server-side hidden service rendezvous circuit.

Used by hidden services for rendezvous connections.

Testing

Testing to see if we’re reachable as a relay.

Self-test circuits to verify relay reachability.

Controller

Circuit that was built by a controller.

Explicitly created via the control protocol.

MeasureTimeout

Circuit being kept around to measure timeout.

Used for circuit build time measurement.

HsVanguards

Constructed in advance for hidden service vanguards.

Pre-built circuits for vanguard protection.

PathBiasTesting

Probing if circuits are being maliciously closed.

Used to detect path bias attacks.

CircuitPadding

Circuit is unused but remains open to disguise closure time.

Padding circuits to prevent traffic analysis.

Trait Implementations

impl Clone for CircPurpose

fn clone(&self) -> CircPurpose

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CircPurpose

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CircPurpose

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CircPurpose

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CircPurpose

fn eq(&self, other: &CircPurpose) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
