Code to fetch, store, and update Tor directory information.
This crate is part of Arti, a project to implement Tor in Rust.
In its current design, Tor requires a set of up-to-date authenticated directory documents in order to build multi-hop anonymized circuits through the network.
This directory manager crate is responsible for figuring out which directory information we lack, downloading what we're missing, and keeping a cache of it on disk.
mmap (default) -- Use memory mapping to reduce the memory load for
reading large directory objects from disk.
routerdesc -- (Incomplete) support for downloading and storing
router descriptors.
compression (default) -- Build support for downloading compressed
documents. Requires a C compiler.
bridge-client: Provide APIs used to fetch
and use bridge information.
full -- Enable all features above.
static -- Try to link with a static copy of sqlite3.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.
dirfilter: enable an experimental mechanism to modify incoming
directory information before it is used.
experimental: Enable all the above experimental features.
features work reliably. To be explicit: if you want cargo update
to only make safe changes, then you cannot enable these
features.
