Protocol v1 Specification

The following is the specification of the Hydra Protocol for version 1. Connections with Hydra are done over TCP/IP, with a small and simple header. How individual plugins handle the communication once connection has been established, is none of Hydras concern.

Offset	Datatype	Name	Description
0x00	int64	Protocol version	Specifies which version of the protocol to be used.
0x08	int32	PluginID length	The length in bytes that the plugin ID string take up.
0x0C	String	PluginID	The plugin ID as a UTF-8 encoded string, the length is specified in the previous integer.
0x0C + PluginID length	int64	InstanceID	Optional: If specified hydra will connect to an existing plugin instance, instead of instanciating a new.
