英文:
Kubernetes undefined noderesources.preFilterState
问题
我正在重写Kubernetes的NodeResourcesFit插件的逻辑，我想像这个链接中的代码一样使用preFilterState：https://github.com/kubernetes/kubernetes/blob/419e0ec3d2512afd8c1f35a44862f856bc4ac10f/pkg/scheduler/framework/plugins/noderesources/fit.go#L91，所以我在代码中导入了它：
import "k8s.io/kubernetes/pkg/scheduler/framework/plugins/noderesources"
然后像这样使用它：
s, ok := c.(*noderesources.preFilterState)
然而，我遇到了一个错误：undefined: noderesources.preFilterState
我对Kubernetes不太熟悉，所以不知道哪里出错了。谢谢你的耐心。
我尝试打印noderesources.Name，但也失败了。

I am rewriting the logic of Kubernetes' NodeResourcesFit plugin, I want to use preFilterState like <https://github.com/kubernetes/kubernetes/blob/419e0ec3d2512afd8c1f35a44862f856bc4ac10f/pkg/scheduler/framework/plugins/noderesources/fit.go#L91>, so I import it in the code:
import "k8s.io/kubernetes/pkg/scheduler/framework/plugins/noderesources"
and use it just like:
s, ok := c.(*noderesources.preFilterState)
However I get an error: undefined: noderesources.preFilterState
I am not familiar with Kubernetes, so I don't know what is wrong with it. Thanks for your patience.
I try to print noderesources.Name but it failed too.

根据你提供的链接，preFilterState没有被导出，因此无法从包的外部访问。这与Kubernetes无关，而是与Go语言有关：
- 示例：https://go.dev/tour/basics/3
- 文档：https://go.dev/doc/effective_go#names
我有一种感觉你刚开始学习Go语言，我建议你先熟悉一下这门语言的基础知识，可以使用一个带有智能感知功能的集成开发环境（IDE）或文本编辑器，这样你就能知道可以调用哪些函数和变量。
英文:
According to the link you're providing, preFilterState is not exported and therefore not accessible from the outside of the package.
It has nothing to do with Kubernetes but with go:
I have a feeling you are starting with go, I recommend you play a bit with the fundamentals of the language and maybe use an IDE/Text editor with intellisense to be able to know what you can and cannot call.
