Crate tor_consdiff

tor-consdiff

Restricted ed diff and patch formats for Tor.

Overview

This crate is part of Arti, a project to implement Tor in Rust. Tor uses a restricted version of the “ed-style” diff format to record the difference between a pair of consensus documents, so that clients can download only the changes since the last document they have.

This crate provides a function to apply one of these diffs to an older consensus document, to get a newer one.

TODO: Eventually, when we add relay support, we will need to generate these diffs as well as consume them.
