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 versioning[^1] 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.

[^1]: Remember, semantic versioning is what makes various cargo features work reliably. To be explicit: if you want cargo update to only make safe changes, then you cannot enable these features.
