+//! HTTP cookie parsing and cookie jar management.
+//!
+//! This crates provides the [`Cookie`] type, representing an HTTP cookie, and
+//! the [`CookieJar`] type, which manages a collection of cookies for session
+//! management, recording changes as they are made, and optional automatic
+//! cookie encryption and signing.
+//!
+//! # Usage
+//!
+//! Add the following to the `[dependencies]` section of your `Cargo.toml`:
+//!
+//! ```toml
+//! cookie = "0.16"
+//! ```
+//!
+//! # Features
+//!
+//! This crate exposes several features, all of which are disabled by default:
+//!
+//! * **`percent-encode`**
+//!
+//! Enables _percent encoding and decoding_ of names and values in cookies.
+//!
+//! When this feature is enabled, the [`Cookie::encoded()`] and
+//! [`Cookie::parse_encoded()`] methods are available. The `encoded` method
+//! returns a wrapper around a `Cookie` whose `Display` implementation
+//! percent-encodes the name and value of the cookie. The `parse_encoded`
+//! method percent-decodes the name and value of a `Cookie` during parsing.
+//!
+//! * **`signed`**
+//!
+//! Enables _signed_ cookies via [`CookieJar::signed()`].
+//!
+//! When this feature is enabled, the [`CookieJar::signed()`] method,
+//! [`SignedJar`] type, and [`Key`] type are available. The jar acts as "child
+//! jar"; operations on the jar automatically sign and verify cookies as they
+//! are added and retrieved from the parent jar.
+//!
+//! * **`private`**
+//!
+//! Enables _private_ (authenticated, encrypted) cookies via
+//! [`CookieJar::private()`].
+//!
+//! When this feature is enabled, the [`CookieJar::private()`] method,
+//! [`PrivateJar`] type, and [`Key`] type are available. The jar acts as "child
+//! jar"; operations on the jar automatically encrypt and decrypt/authenticate
+//! cookies as they are added and retrieved from the parent jar.
+//!
+//! * **`key-expansion`**
+//!
+//! Enables _key expansion_ or _key derivation_ via [`Key::derive_from()`].
+//!
+//! When this feature is enabled, and either `signed` or `private` are _also_
+//! enabled, the [`Key::derive_from()`] method is available. The method can be
+//! used to derive a `Key` structure appropriate for use with signed and
+//! private jars from cryptographically valid key material that is shorter in
+//! length than the full key.
+//!
+//! * **`secure`**
+//!
+//! A meta-feature that simultaneously enables `signed`, `private`, and
+//! `key-expansion`.
+//!
+//! You can enable features via `Cargo.toml`:
+//!
+//! ```toml
+//! [dependencies.cookie]
+//! features = ["secure", "percent-encode"]
+//! ```
