//! High-level functionality for accessing the Tor network as a client.
//!
//! (Note that this crate is called `tor-client` in some other places,
//! since we didn't know about the conflict with `tor_client`. We will
//! clean all of this up somehow before the next release.)
//!
//! # Overview
//!
//! The `arti-tor-client` crate aims to provide a safe, easy-to-use API for
//! applications that want to use Tor network to anonymize their
//! traffic. It hides most of the underlying detail, letting other
//! crates decide how exactly to use the Tor crate.
//!
//! This crate is part of
//! [Arti](https://gitlab.torproject.org/tpo/core/arti/), a project to
//! implement [Tor](https://www.torproject.org/) in Rust.
//! It is the highest-level library crate in
//! Arti, and the one that nearly all client-only programs should use.
//! Most of its functionality is provided by lower-level crates in Arti.
//!
//! ## ⚠️Warnings ⚠
//! ️
//! **Do not expect ANY privacy from this code yet.**
//!
//! Arti is a work in progress, and there are currently certain
//! missing features that _will_ make it far less private than the
//! standard Tor implementation. In fact, the absence of these makes
//! Arti clients vulnerable to certain classes of well known attacks
//! that the standard Tor implementation defends against.
//!
//! At present, do not expect Arti to give you _any privacy at all_. (We'll
//! remove or soften this warning once we're more confident in our privacy.)
//!
//! **Do not use this code in production yet.**
//!
//! All of the APIs for this crate, and for Arti in general, are not
//! the least bit stable. If you use this code, please expect your
//! software to break on a regular basis.
//!
//! ## Design considerations, privacy considerations.
//!
//! As we build the APIs for this crate, we've been aiming for
//! simplicity and safety: we want it to be as easy as possible to use
//! `tor-client`, while trying to make certain kinds of privacy or security
//! violation hard to write accidentally.
//!
//! Privacy isn't just a drop-in feature, however. There are still
//! plenty of ways to accidentally leak information, even if you're
//! anonymizing your connections over Tor. We'll try to document
//! those in a user's guide at some point as Arti becomes more mature.
//!
//! # Using `tor-client`
//!
//! The `tor-client` crate provides an async Rust API. It is
//! compatible with the `tokio` and `async_std` asynchronous backends.
//!
//! TODO: Good examples here once the crate setup API is more simple.
//!
//! # Feature flags
//!
//! `tokio` -- (Default) Build with support for the Tokio backend.
//!
//! `async-std` -- Build with support for the `async_std` backend.
//!
//! `experimental-api` -- Build with experimental, unstable API support.
//! Note that these APIs are NOT covered by semantic versioning guarantees:
//! we might break them or remove them between patch versions.
