Summary of Changes
Hello @gaby, 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 is solely focused on enhancing the documentation for the RequestID middleware. The primary goal is to provide clearer and more comprehensive information regarding how the middleware handles request identifiers, specifically detailing their propagation from incoming headers and their storage within the request context, ensuring users have a better understanding of its behavior.
Highlights
- Documentation Clarity: I've updated the main description of the
RequestIDmiddleware to clearly state that it generates or propagates a request identifier. Crucially, the documentation now also specifies that the ID is added to response headers and stored in the request context, providing a more complete picture of its functionality. - Header Reuse Explanation: A new sentence has been added to clarify that if an incoming request already contains the configured
RequestIDheader, its value will be reused instead of generating a new one. This addresses a common point of confusion regarding ID propagation. - Wording Improvement: I've made a minor wording adjustment in the 'Usage' section, changing 'After you initiate your Fiber app, you can use the following possibilities:' to 'After initializing your Fiber app, you can use the middleware in the following ways:' for better readability and conciseness.

Code Review
This pull request improves the documentation for the RequestID middleware by clarifying how it handles existing request IDs from incoming requests and where the generated ID is stored. The changes are accurate and significantly improve the documentation's clarity. I've provided one suggestion to make a new explanation even more explicit and helpful to the reader.

While this clarification is a great addition, it could be even more helpful by being more explicit. Mentioning the specific configuration option (Config.Header), its default value, and the alternative behavior (generation) would make the documentation more self-contained and clearer for the user.
| If the incoming request already contains the configured header, its value is reused instead of generating a new one. | |
| If the header (configured in `Config.Header`, defaulting to `X-Request-ID`) is already present in the incoming request, its value is reused. Otherwise, a new ID is generated. |
