Learning Go Programming

Overview of this book

The Go programming language has firmly established itself as a favorite for building complex and scalable system applications. Go offers a direct and practical approach to programming that let programmers write correct and predictable code using concurrency idioms and a full-featured standard library. This is a step-by-step, practical guide full of real world examples to help you get started with Go in no time at all. We start off by understanding the fundamentals of Go, followed by a detailed description of the Go data types, program structures and Maps. After this, you learn how to use Go concurrency idioms to avoid pitfalls and create programs that are exact in expected behavior. Next, you will be familiarized with the tools and libraries that are available in Go for writing and exercising tests, benchmarking, and code coverage. Finally, you will be able to utilize some of the most important features of GO such as, Network Programming and OS integration to build efficient applications. All the concepts are explained in a crisp and concise manner and by the end of this book; you would be able to create highly efficient programs that you can deploy over cloud.

Preface

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 remote procedure calls (RPC).

Binary encoding with gob

The gob package (https://golang.org/pkg/encoding/gob) provides an encoding format that can be used to convert complex Go data types into binary. Gob is self-describing, meaning each encoded data...
