Data Transport through gob

The gob is Go’s format for serializing and deserializing program data in binary format. It is found in the encoding package. Data in this format is called a gob (short for Go binary format). It is similar to Python’s pickle or Java’s Serialization. It is typically used in transporting arguments and results of remote procedure calls (RPCs) (see the rpc package Chapter 13). More generally, it used for data transport between applications and machines. In what way is it different from JSON or XML? The gob was tailored explicitly for working in an environment that is entirely in Go, for example, communicating between two servers written in Go.
