//! The Home Assistant protocol is structured as a simple
//! TCP socket with short binary messages encoded in the protocol buffers format.
//! First, a message in this protocol has a specific format:
//!
//!  * A zero byte.
//!  * VarInt denoting the size of the message object. (type is not part of this)
//!  * VarInt denoting the type of message.
//!  * The message object encoded as a ProtoBuf message
//!
//! The connection is established in 4 steps:
//!
//!  * First, the client connects to the server and sends a [Hello Request](api::HelloRequest)
//!    identifying itself
//!  * The server responds with a [Hello Response](api::HelloResponse) and selects the
//!    protocol version
//!  * After receiving this message, the client attempts to authenticate itself using
//!    the password and a [Connect Request](api::ConnectRequest)
//!  * The server responds with a [Connect Response](api::ConnectResponse) and notifies
//!    of invalid password if necessary.
//!
//! If anything in this initial process fails, the connection must immediately closed
//! by both sides and _no_ disconnection message is to be sent.
