Module formats 

Pixel format constants generated from the installed libcamera/formats.h.

The names and values in this module mirror libcamera::formats for the libcamera version detected at build time. Use these to avoid hand-rolling fourcc/modifier pairs:

// Example:
// let fmt = PixelFormat::parse("NV12").unwrap();
// let info = fmt.info().unwrap();
// assert_eq!(fmt.to_string(), info.name);
