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.
