The problem

I was looking for a way to change the status code of my response and it has been hard to find to me, I based on the next example to create a CORS middleware, but the response status code was always 200 code, instead of 401 (unauthorized), so I had to change the status code manually, but I don't find any way to change it properly.

I also tried to base on this documentation to change the status code, but that doesn't work with my problem, since this example instead of modifying an existing response is creating a new empty response.

Then I noticed the status_mut function in the response struct, but it doesn't have any documentation about how to use it. So I couldn't use it anyway. Later I checked and found this block of code in this GitHub repository and I based on it to change the response status code, and that worked properly. But I think it could be included in the examples, for example, the first one that I mentioned could include this part about how to change the status code

The request

I suggest to add examples about how to use status_mut() to the middleware examples or to another example where it was visible so beginners can easily change the status_mut of a response
