reference.html inconsistent on struct expressions

[tromey]

One part of the reference manual says that empty braces are allowed for struct expressions: https://doc.rust-lang.org/reference.html#structs

Another part says that the braces must contain one or more initializers: https://doc.rust-lang.org/reference.html#struct-expressions

rustc tells me that empty braces are an unstable extension, so one way to resolve the discrepancy would be to mention this in the manual, preferably at both spots.

Yes, this is something that's changed, but the docs haven't.

I would be happy to work with anyone who wants to work on this issue.

I can work on this. The latest compiler doesn't seem to give any kind of a warning related to empty braces - https://is.gd/h7oleb

[steveklabnik]

That'd be great! Since the time this issue was filed, braces are okay to use in stable. So these spots should be updated to reflect that.

[abhijeetbhagat]

I am not sure if this is the only file which requires the update.

[steveklabnik]

I don't believe so, or at least, not for this ticket. There's a lot of ways the reference can improve.

@steveklabnik Was this fixed by #34742?

@steveklabnik I believe this was fixed by pr #34742. I see no inconsistencies in the book or reference.

Closing! Thanks @apasel422 @achan1989
