Missing help on pattern guard

[GuillaumeGomez]

One the following code, suggesting to use ref keyword would be very appreciated I think.

Hmm, need to be careful though... if the pattern guard actually consumes the value then you'll get a bug report for the compiler recommending wrong code: http://is.gd/zGSj9C

[GuillaumeGomez]

Hum... Then maybe an update of the error code explanation would be more appropriate to show the differences between the two cases.

Hmm, using ref keyword is helpful here.
But in this example, what will be helpful except use &self in consume?

[GuillaumeGomez]

@mrmiywj: That's the point that durka pointed out. So that's why I propose to only change error explanation to reflect both cases.

[mrmiywj]

You mean that if in the context the ownership will not be taken, it is suggested to use ref here?
Hmm, if it's right, I think it's a easy job and I can change the explanation to reflect both cases with some examples. U should not waste time on this dirty job.

[GuillaumeGomez]

Haha! Please do it if you want. cc me on the PR so I can review it (and don't forget to say "Fixes #33247").
