rift-mesh

Mesh networking, session management, and E2EE for the riftd P2P protocol.

Part of the riftd project — serverless P2P voice + text chat over UDP.

What's in this crate?

rift-mesh is the heart of riftd's networking:

• Mesh Topology — Every peer connects to every peer
• Noise Sessions — Encrypted channels using Noise_XX
• E2EE — End-to-end encryption for all messages
• NAT Traversal — Automatic hole punching with fallback
• Peer Relay — Route through peers when direct fails
• Session Management — Handle joins, leaves, reconnects

Usage

use rift_mesh::{MeshNode, MeshConfig};

let config = MeshConfig::default();
let node = MeshNode::new(config).await?;

// Join a channel
node.join(channel_id).await?;

// Send a message
node.send_chat(peer_id, "Hello!").await?;

// Handle incoming messages
while let Some(event) = node.next_event().await {
    match event {
        MeshEvent::Chat { from, message } => { /* ... */ }
        MeshEvent::Voice { from, frame } => { /* ... */ }
        MeshEvent::PeerJoined(peer) => { /* ... */ }
    }
}

Features

• predictive-rendezvous (default) — Enable SRT-based NAT traversal
