6//!
7//! ```shell
8//! $ bindgen virtio_video.h              \
9//!     --allowlist-type "virtio_video.*" \
10//!     --allowlist-var "VIRTIO_VIDEO_.*" \

14//! $ sed -i "s/__u/u/g" protocol.rs
15//! $ sed -i "s/__le/Le/g" protocol.rs
16//! ```
17//!
18//! The main points of the manual modifications are as follows:
19//! * Removed `hdr` from each command struct so that we can read the header and a command body
20//!   separately. (cf. [related discussion](https://markmail.org/message/tr5g6axqq2zzq64y))
21//! * Derive implementations of zerocopy traits for each struct as needed.
22//! * Added GET_PARAMS_EXT and SET_PARAMS_EXT to allow querying and changing the resource type
23//!   dynamically.
24//! * Moved some definitions such as virtio_video_config to device_constants to make them visible to
25//!   vhost-user modules, and also pub-use them.
