//! Transport implementations for Steam API communication.
//!
//! This module provides transport abstractions for communicating with Steam's
//! services. Two built-in transports are available:
//!
//! - [`WebApiTransport`]: HTTP-based transport using `api.steampowered.com`
//! - [`WebSocketCMTransport`]: WebSocket transport for direct CM server
//!   communication
//!
//! # Custom Transports
//!
//! The [`Transport`] enum is currently closed (not extensible) to provide a
//! simpler API. If you need custom transport behavior, you can:
//!
//! 1. Use [`WebApiTransport::with_client`] to provide a custom
//!    `reqwest::Client` with custom configuration (timeouts, proxies, etc.)
//! 2. Use [`WebSocketCMTransport::with_options`] to provide a custom CM server
//!    provider
//!
//! For more advanced customization, consider wrapping the existing transports
//! or contributing a new transport variant to the crate.
