Golang中的var()是什么意思

I go though the code generated by go-swagger, found follow code:

// NewReceiveLearningLabActsParams creates a new ReceiveLearningLabActsParams object
// with the default values initialized.
func NewReceiveLearningLabActsParams() ReceiveLearningLabActsParams {
    var ()
    return ReceiveLearningLabActsParams{}
}

I noticed here:

var ()

I totally not understand what's the means, could anyone help me understand this code? thanks

    In Go this is a shorthand for defining variables in bulk. Instead of having to write var in front of every variable declaration, you can use a var declaration block.

    For example:

    var (
        a,b,c string = "this ", "is ","it "
        e,f,g int = 1, 2, 3
    )
    

    is the same as

    var a,b,c string = "this ", "is ","it "
    var d,e,f int = 1, 2, 3
    

    The var () in your code example simply states that no variables were declared.

    Refer to the official Go documentation for more information.
