1  //! Message module for multi-transport messaging.
 2  //!
 3  //! This module extends the existing message functionality with support for
 4  //! multi-transport routing. It re-exports types from `protocol::messages`
 5  //! and adds new types for transport-agnostic messaging.
 6  //!
 7  //! # Types
 8  //!
 9  //! - **From `protocol::messages`**: Core message types (PlaintextMessage, EncryptedMessage, etc.)
10  //! - **MessageEnvelope**: Wrapper for routing messages across transports
11  //! - **Routing**: Types for address resolution and delivery tracking
12  //!
13  //! # Usage
14  //!
15  //! ```ignore
16  //! use dead_drop_core::message::{
17  //!     // Core message types
18  //!     PlaintextMessage, EncryptedMessage, encrypt_message,
19  //!     // Multi-transport support
20  //!     MessageEnvelope, ContactRoutes, DeliveryStatus,
21  //! };
22  //! ```
