Pointer Slices Example

This example demonstrates how to use pointers and slices of pointers with genstruct.

Features Demonstrated

1. Single pointer references (*Author)
2. Slices of pointer references ([]*Comment)
3. Bi-directional references between different types

Data Model

This example uses three related types:

• Author: Represents a content creator
• Comment: User feedback with a pointer to its Author
• Article: A blog article with a pointer to its Author and a slice of pointers to Comments

Relationships

• Each Article has one Author (single pointer: *Author)
• Each Article has multiple Comments (slice of pointers: []*Comment)
• Each Comment has one Author (single pointer: *Author)

Running the Example

go run main.go

This will generate articles_generated.go with constants, variables, and slices for all the data, including proper pointer references.

Generated Code Usage

The generated code enables you to:

1. Access specific articles via their constants: ArticleUnderstandingPointerSlices
2. Navigate directly to their author: ArticleUnderstandingPointerSlices.Author.Name
3. Access all comments: ArticleUnderstandingPointerSlices.Comments
4. Navigate from comments back to their authors: ArticleUnderstandingPointerSlices.Comments[0].Author.Name

Testing

Run the tests with:

go test -v
