+/// Transport policies provide network connectivity and timers
+/**
+ * ### Connection Interface
+ *
+ * Transport connection components needs to provide:
+ *
+ * **init**\n
+ * `void init(init_handler handler)`\n
+ * Called once shortly after construction to give the policy the chance to
+ * perform one time initialization. When complete, the policy must call the
+ * supplied `init_handler` to continue setup. The handler takes one argument
+ * with the error code if any. If an error is returned here setup will fail and
+ * the connection will be aborted or terminated.
+ *
+ * WebSocket++ will call init only once. The transport must call `handler`
+ * exactly once.
+ *
+ * **async_read_at_least**\n
+ * `void async_read_at_least(size_t num_bytes, char *buf, size_t len,
+ * read_handler handler)`\n
+ * start an async read for at least num_bytes and at most len
+ * bytes into buf. Call handler when done with number of bytes read.
+ *
+ * WebSocket++ promises to have only one async_read_at_least in flight at a
+ * time. The transport must promise to only call read_handler once per async
+ * read.
+ *
+ * **async_write**\n
+ * `void async_write(const char* buf, size_t len, write_handler handler)`\n
+ * `void async_write(std::vector<buffer> & bufs, write_handler handler)`\n
+ * Start a write of all of the data in buf or bufs. In second case data is
+ * written sequentially and in place without copying anything to a temporary
+ * location.
+ *
+ * Websocket++ promises to have only one async_write in flight at a time.
+ * The transport must promise to only call the write_handler once per async
+ * write
+ *
+ * **set_handle**\n
+ * `void set_handle(connection_hdl hdl)`\n
+ * Called by WebSocket++ to let this policy know the hdl to the connection. It
+ * may be stored for later use or ignored/discarded. This handle should be used
+ * if the policy adds any connection handlers. Connection handlers must be
+ * called with the handle as the first argument so that the handler code knows
+ * which connection generated the callback.
+ *
+ * **set_timer**\n
+ * `timer_ptr set_timer(long duration, timer_handler handler)`\n
+ * WebSocket++ uses the timers provided by the transport policy as the
+ * implementation of timers is often highly coupled with the implementation of
+ * the networking event loops.
+ *
+ * Transport timer support is an optional feature. A transport method may elect
+ * to implement a dummy timer object and have this method return an empty
+ * pointer. If so, all timer related features of WebSocket++ core will be
+ * disabled. This includes many security features designed to prevent denial of
+ * service attacks. Use timer-free transport policies with caution.
+ *
+ * **get_remote_endpoint**\n
+ * `std::string get_remote_endpoint()`\n
+ * retrieve address of remote endpoint
+ *
+ * **is_secure**\n
+ * `void is_secure()`\n
+ * whether or not the connection to the remote endpoint is secure
+ *
+ * **dispatch**\n
+ * `lib::error_code dispatch(dispatch_handler handler)`: invoke handler within
+ * the transport's event system if it uses one. Otherwise, this method should
+ * simply call `handler` immediately.
+ *
+ * **async_shutdown**\n
+ * `void async_shutdown(shutdown_handler handler)`\n
+ * Perform any cleanup necessary (if any). Call `handler` when complete.
