Reverse-initiated, multiplexed services over QUIC.

quic-reverse is a library that enables servers to initiate streams back to clients over an existing QUIC connection. This is useful for scenarios where:

• Clients are behind NAT and cannot accept incoming connections
• Edge devices need to expose services to a central server
• Reverse tunneling is required without opening inbound ports

Architecture

The library sits atop an existing QUIC connection and adds:

• An explicit control plane for stream lifecycle management
• Reverse-initiated stream semantics
• Service multiplexing via service identifiers
• Well-defined negotiation, backpressure, and error handling

Example

use quic_reverse::{Session, Config, Role};

// Wrap an existing QUIC connection
let session = Session::new(connection, Role::Client, Config::default());

// Start the session (performs negotiation)
let mut handle = session.start().await?;

// Open a reverse stream to a service
let (send, recv) = handle.open("ssh", Metadata::Empty).await?;
