Summary of Changes
Hello @cuiweixie, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request refactors the codebase to utilize the reflect.TypeAssert function for type assertions, replacing the older elem.Interface().(*Type) pattern. This change aligns with best practices for Go's reflection API, as indicated by the linked Go issue, aiming for a more robust and potentially safer way to perform type assertions.
Highlights
- Reflection API Update: Replaced direct interface type assertion (
elem.Interface().(*tls.Config)) with the more modern and type-safereflect.TypeAssert[*tls.Config](elem)inhelpers.go.

Code Review
This pull request correctly refactors a type assertion to use the reflect.TypeAssert function. This is a good improvement as it leverages a more modern and efficient API available in recent Go versions. The change is straightforward and has been implemented correctly. I have reviewed the code and have no further suggestions.
