Where is the builder pattern described in the book?

[ckaran]

Rust references the 'builder pattern' in a number of locations, so I decided to see what the book had to say about it. As near as I can tell, it isn't described in the current edition. The only reference I found was via google to the 1.0.0 docs, and a couple of closed bug reports (1 and 2) saying that it was being worked into Chapter 17, but other than that, nothing. Did it get lost somewhere?

Yes, we decided to take Chapter 17 in a different direction, and we don't have plans to add it back at this point. There are a LOT of patterns we could have covered but we don't have room to discuss them all-- please see the rust-unofficial/patterns repo for documentation on them. Thanks!

I understand why you wouldn't want to list all design patterns, but I think the builder pattern is special in rust; it is referenced a lot, and rust has its own idiomatic way of using it. There needs to be a more official place for it than rust-unofficial.

There is an explanantion under Type Safety of the api guidelines.

Thank you for the link @platy.

I think my bigger concern is that all these ideas are well-documented, but finding them can be difficult. AFAIK, there is no direct link from the docs page to things like the rust API guidelines. But that's a problem for a separate issue...

I'm a bit concerned about that too, I came across that page (and the API guidelines) for the first time last week. When trying to find it again today I landed here , I thought that link might help others find it. I think there could be more cross linking between the books.

For what it's worth, I opened a new issue regarding documentation here.
