Learning Go Programming

Encoding and decoding data

Another common aspect of IO in Go is the encoding of data, from one representation to another, as it is being streamed. The encoders and decoders of the standard library, found in the encoding package (https://golang.org/pkg/encoding/), use the io.Reader and io.Writer interfaces to leverage IO primitives as a way of streaming data during encoding and decoding.

Go supports several encoding formats for a variety of purposes including data conversion, data compaction, and data encryption. This chapter will focus on encoding and decoding data using the Gob and JSON format for data conversion. In Chapter 11, Writing Networked Programs, we will explore using encoders to convert data for client and server communication using ...
