Meta programming in Go: A step-by-step guide on using Struct Tags

In a recent blog post, Eldius shared their experience with meta programming in Go, specifically focusing on using struct tags. The article provides a comprehensive overview of how to access and utilize custom tags on attributes of a struct.

The author begins by explaining the importance of understanding struct tags in Go programming. They then provide a simple example of how to retrieve the value of a tag prop attribute for each attribute in a struct. This is followed by a simplified encoder that only serializes or deserializes attributes from the "instance mother" (avoiding nested attributes).

The post concludes by highlighting the need to manually extract information from strings when dealing with tags having properties, such as validation rules.
