tokio-vsock

Asynchronous Virtio socket support for Rust. The implementation is based off of Tokio and Mio's TCPListener and TCPStream interfaces.

tokio-vsock is for the most part pre-alpha quality, so there are probably sharp edges. Please test it thoroughly before using in production. Happy to receive pull requests and issue reports.

Use Cases

The most common use case for tokio-vsock would be writing agents for microvm applications. Examples would include container runtimes.

Usage

Refer to the crate documentation.
