The Go programming language has a package called “gob” that provides a new encoding for transmitting data structures across a network or storing them in a file. While there are existing formats like JSON and XML, the gob package offers a simpler and potentially more efficient option for Go-specific environments. The package was designed with goals of being easy to use and efficient, using a binary encoding instead of textual representations. Gobs are self-describing, meaning the entire stream can be parsed even without prior knowledge of its contents. The package also supports defining custom encodings and provides flexibility in handling values and types.
