//! `CoW` Protocol order app-data — metadata schema and hash generation.
//!
//! App-data is a `bytes32` field in every `CoW` order that encodes a
//! `keccak256` hash of a JSON document describing the order's intent,
//! referral, UTM codes, interaction hooks, and more.
//!
//! # Submodules
//!
//! | Module | Purpose |
//! |---|---|
//! | [`types`] | Rust types matching the JSON schema (v1.14.0) |
//! | [`hash`] | Deterministic JSON serialisation and `keccak256` hashing |
//! | [`cid`] | Bidirectional `appDataHex` ↔ IPFS `CIDv1` conversion |
//! | [`ipfs`] | IPFS fetch/upload helpers and the [`MetadataApi`] facade |
//! | [`schema`] | Runtime JSON Schema validation against the bundled upstream spec |
//! | `validation` | Business-rule constraint checks (`appCode` length, `bps` caps, …) |
//!
//! # Quick start
//!
//! ```rust
//! use cow_rs::app_data::{AppDataDoc, MetadataApi};
//!
//! let api = MetadataApi::new();
//! let doc = api.generate_app_data_doc("MyApp");
//! let info = api.get_app_data_info(&doc).unwrap();
//! println!("appData hex : {}", info.app_data_hex);
//! println!("CID         : {}", info.cid);
//! ```
//!
//! # Building app-data for an order
//!
//! ```rust
//! use cow_rs::app_data::{Metadata, Quote, build_app_data_doc, build_order_app_data};
//!
//! // Simple: just an app code
//! let hex = build_order_app_data("MyDApp").unwrap();
//!
//! // With metadata: slippage, partner fees, hooks, …
//! let meta = Metadata::default().with_quote(Quote::new(50));
//! let hex = build_app_data_doc("MyDApp", meta).unwrap();
//! ```
