处理 go 中的多个错误的最佳方法是什么？

Question

Let's say I have the following function in go:

func SomeFunction() error {

    a, err := Step1()

    if err != nil {
        return err
    }

    b, err := Step2(a)

    if err != nil {
        return err
    }

    c, err := Step3(b)

    if err != nil {
        return err
    }

    // Etc etc

    return nil
}

I have to handle each error individually, and I feel like this results in very repetitive code. I was wondering what the correct way to handle errors in a situation like this would be.
