Crate cookie

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:

cookie = "0.18"

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:

[dependencies.cookie]
features = ["secure", "percent-encode"]

Re-exports

• pub use time;

Modules

• prefix
  Implementation of HTTP RFC6265 draft cookie prefixes.

Structs

• Cookie
  Representation of an HTTP cookie.
• CookieBuilder
  Structure that follows the builder pattern for building Cookie structs.
• CookieJar
  A collection of cookies that tracks its modifications.
• Delta
  Iterator over the changes to a cookie jar.
• Display
  Wrapper around Cookie whose Display implementation either percent-encodes the cookie’s name and value, skips displaying the cookie’s parameters (only displaying it’s name and value), or both.
• Iter
  Iterator over all of the cookies in a jar.
• Keyprivate or signed
  A cryptographic master key for use with Signed and/or Private jars.
• PrivateJarprivate
  A child cookie jar that provides authenticated encryption for its cookies.
• SignedJarsigned
  A child cookie jar that authenticates its cookies.
• SplitCookies
  An iterator over cookie parse Results: Result<Cookie, ParseError>.

Enums

• Expiration
  A cookie’s expiration: either a date-time or session.
• KeyErrorprivate or signed
  An error indicating an issue with generating or constructing a key.
• ParseError
  Enum corresponding to a parsing error.
• SameSite
