我有一個函數(shù)，它接受指向任何切片的指針，并且所述參數(shù)的類型為interface{}。我需要確保指針不指向切片nil。package mainimport (    "fmt")type Dog struct {    Name string    Age  int}func main() {    var slicePointer interface{}    // We only want slices that were initialized with `make()`.    dogs1 := make([]Dog, 0)    fmt.Println("dogs1 == nil:", dogs1 == nil)    slicePointer = &dogs1    fmt.Println("slicePointer == nil:", slicePointer == nil)    fmt.Println("-----")    // This needs to be caught, as the slice is `nil`.    var dogs2 []Dog    fmt.Println("dogs2 == nil:", dogs2 == nil)    slicePointer = &dogs2    fmt.Println("slicePointer == nil:", slicePointer == nil)}輸出：dogs1 == nil: falseslicePointer == nil: false-----dogs2 == nil: trueslicePointer == nil: false   有沒有辦法在 Golang 中進行這樣的檢查？
