arcbox-virtio-fs 0.4.9

//! `VirtIO` filesystem device (virtio-fs).
//!
//! This implements the high-performance shared filesystem using virtiofs
//! protocol for host-guest file sharing.
//!
//! # Architecture

//!
//! ## Module layout
//!
//! - `protocol`: FUSE wire-protocol constants
//! - `request`: `FuseRequest` / `FuseResponse` envelopes
//! - `session`: `FuseSession` — INIT handshake + negotiated state
//! - `handler`: `FuseRequestHandler` trait
//! - `device`: `FsConfig`, `VirtioFs`, `VirtioDevice` impl
