Tuple struct syntax is confusing in chapter 15

[schlamar]

The tuple struct is just explained very shortly in textual form without an example accessing the elements (ch05-01-defining-structs). So when I first saw self.0 (in ch15-02-deref) I was very confused.

Plus I couldn't find anything helpful by searching "self.0" in the book. There should be a small example using tuple structs with method, probably in ch05-03-method-syntax.

Other people should decide finally, but I think it isn't necessary to explain this. You access a tuple struct's members just like you access a normal tuple's members. The struct just allows you to enlist the compiler's help to differentiate between two pieces of data with a similar representation in memory, but different semantic meanings. In all other regards, it works just like a tuple, and accessing tuple members is explained quite well.

[schlamar]

Yeah, it's obvious how a tuple struct works if you have seen them in practice.

However, in my case, I haven't seen a tuple struct and how it's used in practice until Chapter 15. So seeing self.0 for the first time, this was very confusing and it took some amount of time finding out what self.0 is actually doing.

[L0uisc]

My point is that the .0 syntax is explained quite well and with an example in ch 3.2 w.r.t. tuples. Mentioning that tuple structs work exactly like tuples except for being a distinct type from other tuples or tuple structs with fields of the same type and order in ch 5.1 is maybe not a bad idea, though.

We could add a back reference.
