What are the best practices for encapsulation in Go?

Encapsulation in Go involves using unexported types and methods to hide implementation details. This helps in maintaining a clean API.

Can you give me an example of how to implement encapsulation in a Go struct?

Sure! You can define a struct with unexported fields and provide exported methods to interact with those fields. For example:

type person struct {
    name string // unexported
    age  int    // unexported
}

func (p *person) SetName(name string) {
    p.name = name
}

func (p *person) GetName() string {
    return p.name
}

This way, the name and age fields are not accessible directly from outside the package.

What are the benefits of using encapsulation in my Go projects?

Encapsulation helps in reducing complexity, improving code maintainability, and protecting the integrity of your data by controlling access to it.

Are there any common mistakes to avoid when using encapsulation in Go?

Yes, common mistakes include overexposing methods, not using interfaces effectively, and failing to consider the package structure, which can lead to tight coupling.
