理解內存洩漏在GO Slice

s：= []它： 長度變為1，但襯里數組仍未觸及。第二個元素中未使用的指針仍是數組的一部分。 Since it's not being referred to by any slice, it becomes inaccessible and cannot be freed by the garbage collector, resulting in a memory leak.

With a slice of non-pointers ([]int):

t := []int{1, 2}

s := []*int{new(int), new(int)}

，即使Slice僅保留Book1，Book2的作者和標題字符串仍在存儲器中作為數組的一部分。為了防止這種情況，請在切片之前為book2分配零值：

s = s[:1]

General Rule

To avoid memory leaks, aim to zero out elements that refer to memory outside the slice's backing array.例如，具有指針，切片或其他復雜數據結構的字段的結構應在重新固定之前歸零以切斷外部參考。
