(c *Collection[T]) Filter 无效的问题

[attson]

过滤应该和比较没有关系吧，直接使用入参函数就好了？

[attson]

	items := []Item{
		{Id: 1},
		{Id: 2},
		{Id: 3},
		{Id: 4},
		{Id: 5},
	}

	newCollection := collection.NewCollection(items)

	filter := newCollection.Filter(func(item Item, key int) bool {
		return item.Id == 2
	})

	fmt.Println(filter)
	fmt.Println(newCollection)

&{[{1} {2} {3} {4} {5}] 0xc0000a8030 0x494aa0 }
&{[{1} {2} {3} {4} {5}] 0xc0000a8030 0x494aa0 }
