§tor-relay-selection
Logic to select Tor relays for specific purposes
§Overview
The tor-relay-selection
crate provides higher-level functions
in order to select Tor relays for specific purposes,
or check whether they are suitable for those purposes.
It wraps lower-level functionality from tor-netdir
.
This crate is part of Arti, a project to implement Tor in Rust.
§Design
Our main types are RelayUsage
, RelayExclusion
, RelayRestriction
, and RelaySelector
.
A RelayUsage
answers the question “what is this relay for?”
A RelayExclusion
excludes one or more relays
as having already been selected,
or as sharing families with already-selected relays.
A RelayRestriction
imposes additional restrictions on a relay.
A RelaySelector
is a collection of a usage, an exclusion, and any number of restrictions.
In a RelaySelector
, usages and restrictions can be strict or flexible.
If we fail to pick a relay, and there are any flexible usages/restrictions,
then we remove those usages/restrictions to produce a relaxed selector
and we try again.

Modules§
- config 🔒Define configuration structures used for relay selection.
- Define different restrictions that can be applied to relays.
- selector 🔒Logic for selecting relays from a network directory, and reporting the outcome of such a selection.
- Declare the TargetPort type.
- usage 🔒Define a type describing how we’re going to use a relay.
Structs§
- A set of relays that we must not use when picking a given relays.
- A restriction that we use when picking relays.
- Configuration object for building relay restrictions.
- Description of the requirements that a relay must implement in order to be selected.
- Description for how we plan to use a single relay.
- Information about how a given selection was generated.
- A port that we want to connect to as a client.
Traits§
- A property that can be provided by relays.
