+//! This crate contains a JPEG decoder.
+//!
+//! # Examples
+//!
+//! ```
+//! use jpeg_decoder::Decoder;
+//! use std::fs::File;
+//! use std::io::BufReader;
+//!
+//! let file = File::open("tests/reftest/images/extraneous-data.jpg").expect("failed to open file");
+//! let mut decoder = Decoder::new(BufReader::new(file));
+//! let pixels = decoder.decode().expect("failed to decode image");
+//! let metadata = decoder.info().unwrap();
+//! ```
+//!
+//! Get metadata from a file without decoding it:
+//!
+//! ```
+//! use jpeg_decoder::Decoder;
+//! use std::fs::File;
+//! use std::io::BufReader;
+//!
+//! let file = File::open("tests/reftest/images/extraneous-data.jpg").expect("failed to open file");
+//! let mut decoder = Decoder::new(BufReader::new(file));
+//! decoder.read_info().expect("failed to read metadata");
+//! let metadata = decoder.info().unwrap();
+//! ```
