AT Protocol Implementation (Rust)

---

[!WARNING] This library is a work in progress. Things will change. Things are incomplete. Things will break. Until the project reaches version 1.0.0, stability will not be guaranteed.

rsky (/ˈrɪski/) is intended to be a full implementation of AT Protocol in the Rust language. Most of the code here are general purpose implementations while some (like rsky-feedgen) are specific to the use cases of the Blacksky community.

What is in here?

Rust Crates:

Crate	Docs	crates.io
rsky-crypto: cryptographic signing and key serialization	README
rsky-identity: DID and handle resolution	README
rsky-lexicon: schema definition language	README
rsky-syntax: string parsers for identifiers	README
rsky-common: shared code	README
rsky-repo: data storage structure, including MST	README

Rust Services:

• rsky-relay: The Relay handles "big-world" networking. It crawls the network, gathering as much data as it can, and outputs it in one big stream for other services to use. It’s analogous to a firehose provider or a super-powered relay node.
• rsky-pds: "Personal Data Server", hosting repo content for atproto accounts. It differs from the canonical Typescript implementation by using Postgres instead of SQLite, s3 compatible blob storage instead of on-disk, and mailgun for emailing. All to make the PDS easier to migrate between cloud hosting providers and more maintainable.
• rsky-feedgen: Bluesky feed generator that closely follows the use cases of the Blacksky community.
• rsky-firehose: Firehose consumer.
• rsky-jetstream-subscriber: Firehose consumer for Jetstream.
• rsky-labeler: Firehose consumer that labels content.
• Cypher: An AT Protocol app-view designed for local-only posting and global views.
• rsky-satnav: "Structured Archive Traversal, Navigation & Verification", a DASL CAR and AT Protocol repository explorer.
