//! # CAT-specific Claims
//!
//! This module provides helper functions and structures for working with
//! Common Access Token (CAT) specific claims as defined in the CAT specification.
//!
//! ## Available CAT Claims
//!
//! - **CATU** (Common Access Token URI) - limits the URI to which the token can provide access
//! - **CATR** (Common Access Token Renewal) - instructions for token renewal
//! - **CATM** (Common Access Token Methods) - limits HTTP methods
//! - **CATREPLAY** - controls token replay behavior
//! - **CATV** (Common Access Token Version) - CAT specification version
//! - **CATPOR** (Common Access Token Probability of Rejection) - probabilistic rate limiting
//! - **CATNIP** (Common Access Token Network IP) - IP address restrictions
//! - **CATALPN** (Common Access Token ALPN) - TLS ALPN protocol restrictions
//! - **CATH** (Common Access Token Header) - HTTP header requirements
//! - **CATGEOISO3166** - geographic country/region restrictions
//! - **CATGEOCOORD** - geographic coordinate restrictions
//! - **CATGEOALT** - altitude restrictions
//! - **CATTPK** (Common Access Token TLS Public Key) - TLS public key pinning
//! - **CATDPOP** (Common Access Token DPoP Settings) - DPoP configuration
//! - **CATIF** (Common Access Token If) - conditional logic
//! - **CATIFDATA** (Common Access Token If Data) - data for conditional evaluation
//! - **CATTPRINT** (Common Access Token TLS Fingerprint) - TLS fingerprint restrictions
//!
//! ## CATU Claim (URI Validation)
//!
//! The CATU claim allows you to specify URI component restrictions. For example:
//!
//! ```rust
//! use common_access_token::{catu, uri_components, cat_keys};
//! use std::collections::BTreeMap;
//!
//! // Create a CATU claim for URI validation
//! let mut catu_components = BTreeMap::new();
//!
//! // Restrict to https scheme
//! catu_components.insert(uri_components::SCHEME, catu::exact_match("https"));
//!
//! // Restrict to example.com host
//! catu_components.insert(uri_components::HOST, catu::suffix_match(".example.com"));
//!
//! // Restrict to paths starting with /api
//! catu_components.insert(uri_components::PATH, catu::prefix_match("/api"));
//!
//! // Create the CATU claim
//! let catu_claim = catu::create(catu_components);
//! ```
//!
//! ## CATM Claim (HTTP Methods)
//!
//! The CATM claim restricts which HTTP methods are allowed:
//!
//! ```rust
//! use common_access_token::{catm, cat_keys};
//!
//! // Create a CATM claim allowing only GET and HEAD methods
//! let allowed_methods = vec!["GET", "HEAD"];
//! let catm_claim = catm::create(allowed_methods);
//! ```
//!
//! ## CATREPLAY Claim (Replay Protection)
//!
//! The CATREPLAY claim controls token replay behavior:
//!
//! ```rust
//! use common_access_token::{catreplay, cat_keys};
//!
//! // Create a CATREPLAY claim that prohibits token reuse
//! let catreplay_claim = catreplay::prohibited();
//!
//! // Or allow token reuse
//! let catreplay_permitted = catreplay::permitted();
//!
//! // Or enable reuse detection
//! let catreplay_detect = catreplay::reuse_detection();
//! ```
//!
//! ## CATR Claim (Token Renewal)
//!
//! The CATR claim provides instructions for token renewal:
//!
//! ```rust
//! use common_access_token::{catr, cat_keys};
//! use common_access_token::current_timestamp;
//!
//! let now = current_timestamp();
//!
//! // Create an automatic renewal claim
//! // This extends expiration by 3600 seconds with a deadline 3000 seconds from now
//! let renewal_params = catr::automatic_renewal(3600, Some((now + 3000) as i64));
//! let catr_claim = catr::create(renewal_params);
//!
//! // Or create a cookie-based renewal claim
//! let cookie_renewal = catr::cookie_renewal(
//!     3600,
//!     Some((now + 3000) as i64),
//!     Some("session"),
//!     Some(vec!["Secure", "HttpOnly"])
//! );
//! ```
//!
//! ## CATTPRINT Claim (TLS Fingerprint)
//!
//! The CATTPRINT claim provides instructions for validating a TLS Fingerprint:
//!
//! ```rust
//! use common_access_token::{cattprint, FingerprintType};
//!
//! // Create a tls fingerprint claim
//! // Possible fingerprint-type values: JA3, JA4, JA4S, JA4H, JA4L, JA4X, JA4SSH, JA4T, JA4TS, JA4TScan
//! // Example JA4 value: t13d1516h2_8daaf6152771_b186095e22b6
//! let cattprint_claim = cattprint::create(FingerprintType::JA4, "t13d1516h2_8daaf6152771_b186095e22b6");
//! ```
