Crate tor_circmgr[−][src]
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.
Limitations
But for now, this tor-circmgr
code is extremely preliminary; its
data structures are all pretty bad, and it’s likely that the API
is wrong too.
Modules
Facilities to build circuits directly, instead of via a circuit manager.
Code to construct paths through the Tor network
Structs
A Circuit Manager (CircMgr) manages a set of circuits, returning them when they’re suitable, and launching them if they don’t already exist.
Configuration for a circuit manager.
Builder for CircMgrConfig
.
Configuration for circuit timeouts, expiration, and so on.
Builder for CircuitTiming
.
A token used to isolate unrelated streams on different circuits.
Rules for building paths over the network.
Builder for PathConfig
.
A set of information about how a stream should be isolated.
Builder for StreamIsolation
.
A port that we want to connect to as a client.
Enums
Represents what we know about the Tor network.
An error returned while looking up or building a circuit
Type Definitions
A Result type as returned from this crate.
