Crate boltr 

BoltR: A pure-Rust Bolt v5.x wire protocol library.

This crate implements the Bolt binary protocol used by Neo4j and compatible graph databases. It provides both server and client components for building Bolt-compatible applications.

Quick start (server)

use std::net::SocketAddr;
use boltr::server::{BoltServer, BoltBackend};

let addr: SocketAddr = "127.0.0.1:7687".parse().unwrap();
BoltServer::builder(backend)
    .max_sessions(100)
    .serve(addr)
    .await?;

Quick start (client)

use boltr::client::BoltSession;

let addr = "127.0.0.1:7687".parse().unwrap();
let mut session = BoltSession::connect(addr).await?;
let result = session.run("RETURN 1 AS n").await?;

for record in &result.records {
    println!("{:?}", record);
}

session.close().await?;

Architecture

• packstream, binary encoding/decoding (PackStream format)
• chunk, message framing (2-byte length-prefixed chunks)
• message, protocol message types and serialization
• types, Bolt value types (scalars, graph structures, temporal, spatial)
• server, server framework with BoltBackend trait
• client, client for connecting to Bolt servers (feature-gated)
