Expand description
§tor-circmgr
circuits through the Tor network on demand.
§Overview
This crate is part of Arti, a project to implement Tor in Rust.
In Tor, a circuit is an encrypted multi-hop tunnel over multiple relays. This crate’s purpose, long-term, is to manage a set of circuits for a client. It should construct circuits in response to a client’s needs, and preemptively construct circuits so as to anticipate those needs. If a client request can be satisfied with an existing circuit, it should return that circuit instead of constructing a new one.
§Compile-time features
-
specific-relay: Support for connecting to a relay via specifically provided connection instructions, rather than using information from a Tor network directory. -
full: Enable all features above.
§Experimental and unstable features
Note that the APIs enabled by these features are NOT covered by semantic versioning1 guarantees: we might break them or remove them between patch versions.
-
experimental-api: Add additional non-stable APIs to our public interfaces. -
experimental: Enable all the above experimental features.

Remember, semantic versioning is what makes various
cargofeatures work reliably. To be explicit: if you wantcargo updateto only make safe changes, then you cannot enable these features. ↩

Structs§
- CircMgr
- A Circuit Manager (CircMgr) manages a set of circuits, returning them when they’re suitable, and launching them if they don’t already exist.

Timing Builder - Builder for
CircuitTiming. - Clock
Skew Events - A stream of
SkewEstimateevents. - First
HopId - A unique cryptographic identifier for a selected guard or fallback directory.
- Path
Config - Rules for building paths over the network.
- Path
