Rod

Rust Object Database.

The decentralized social networking application Iris-messenger syncs over Rod peers by default.

Use

Install Rust first.

Install & run

cargo install rod
rod start

Library

use rod::{Node, Config, Value};
let mut db = Node::new_with_config(Config {
    outgoing_websocket_peers: vec!["wss://some-server-to-sync.with/ws".to_string()],
    ..Config::default()
});
let mut sub = db.get("greeting").on();
db.get("greeting").put("Hello World!".into());
if let Value::Text(str) = sub.recv().await.unwrap() {
    assert_eq!(&str, "Hello World!");
}

Status

15/5/2022:

  • Basic
  • CLI for running the server
  • Incoming websockets
  • Outgoing websockets (env PEERS=wss://some-server-url.herokuapp.com/ws)
  • Multicast (currently size limited to 65KB — large photos in messages will not sync over it)
  • In-memory storage
  • TLS support (env CERT_PATH and KEY_PATH)
  • Advanced deduplication of network messages
  • Publish & subscribe (network messages only relayed to relevant peers)
  • Disk storage (sled.rs)
  • Hash verification for content-addressed data (db.get('#').get(data_hash).put(data))
  • Signature verification of user data (db.get('~' + pubkey).get('profile') ...)
  • Encryption & decryption (usually not needed on the server, but used on the client side in js, like iris private messaging)

Issues

  • Multicast doesn't relay large messages like Iris posts with photos

Develop

cargo install cargo-watch
RUST_LOG=debug cargo watch -x 'run -- start'
cargo test

Watch for code changes and re-run tests that contain the word "stats":

RUST_LOG=debug cargo watch -x 'test stats'
cargo bench
