Stop returning many values: Use Result Structs in Go!
In this video, we will discuss the importance of result structs and how to use them correctly. If you are interested in an overview of Go structs, feel free to watch this video as well: • This is your last video about Golang Structs! .
📝 Description
Result structs are a clean and powerful way to simplify your Go function signatures and make your code easier to maintain. In this video, we'll explore what result structs are, why they're a great alternative to returning multiple values, and how to use them effectively in your Go projects. Through a practical example of building a small web server, you'll see exactly how result structs keep your functions clean, extendable, and beginner-friendly - without sacrificing clarity. You'll learn the following things:
• What result structs are and why they make function signatures cleaner
• How to replace messy multi-value returns with a single structured type
• How to integrate result structs into a small Go Web Server example
• When to consider switching to a result struct
