//! This is a pure-Rust library to parse Exif data.
//! This library can parse TIFF and JPEG images and extract Exif
//! attributes.
//!
//! # Examples
//!
//! An example to parse JPEG/TIFF files:
//!
//! ```
//! for path in &["tests/exif.jpg", "tests/exif.tif"] {
//!     let file = std::fs::File::open(path).unwrap();
//!     let reader = exif::Reader::new(
//!         &mut std::io::BufReader::new(&file)).unwrap();
//!     for f in reader.fields() {
//!         println!("{} {} {:?}", f.tag, f.thumbnail, f.value);
//!     }
//! }
//! ```
