Is there a way to enforce a particular style across a project? From what I've read the abiliity for projects to be internally consistent, even with third party library usage, seems to be one of the big advantages of this design-wise. S

I'm more thinking about the documentation effect of such a wrapper type. Both in the data structure and in the parts of the code that are foced to use unsafe.

I've been wondering if it would make sense to encapsulate internal fields that are part of the unsafe machinery in a type forcing you to use unsafe blocks, even inside the type impl. [edit: Removed note about UnsafeCell since it's

Google suggests "affine memory management" is not yet used as a term.

No, when people's lives are at stake, I extremely disagree about calling that "bikeshedding".

Or to continue the train of thought, what about things that it did ship with that could have been excluded? :) Personally I'm starting to dislike index operations since they can panic (and are the shortest way to access), and I rather

I found consuming Reddit is a lot easier when you treat it like Usenet. So I have RSS subscriptions for the subreddits that interest me in my RSS reader. That also means I can easily organize them myself by topic. In the dev related area ar

It would be a compile-time error saying (in essence) "multiple applicable methods in scope" and giving you a list of the available methods.

Trait methods are only visible when the trait is in scope. So a conflict would only appear when both traits are imported and the method is called, in which case you'll have to disambiguate.

Rust solutions would probably be the following: Some kind of runtime assistance (`Rc<T>`, `Arc<T>` et al), using indices as you mentioned (though with `list.get(index)` you'd still have to deal with the fact that it might n

Ah, good to know. So Nim does static analysis on conditionals where Rust would use an explicit pattern match to get at the contained value. Might be a good example for http://nim-lang.org/manual.html#not-nil-annotation

Out of curiosity: How do you convert from a nilable `Foo` to a `Foo not nil`? As in, what do you do if you have a function maybe returning a `Foo` and want to pass its value to a function taking `Foo not nil`?

It might be a terminology thing. Assuming MyStruct only contains values, it will fully live on my_func's stack and nothing needs deallocating on drop. When take_ownership is called a copy of it's value would be passed in, and the

I think he was more talking about the unique ownership part, especially that values themselves follow the same rules. Which I find fitting, since in Rust, the Box is (at least to me) more about indirection. The single-owner semantics just c

I would say it is familiarity, but in another sense. You can use something like path.file_name().and_then(|f| f.to_str()).unwrap() but that really doesn't buy you much. Where familiarity comes in I believe is in what that line

I'm not really a C guy, but isn't #include about using a module in the current scope? Because Rust's mod is for project structure definition.

Another thing which I don't see often mentioned, but which alleviate most of the compile-time waiting-pain for me (and I'm actually a dynamic language guy) is the fact that since optimizations are usually what takes longest, the c

I should've taken a deeper look at your CSV handling code earlier. That's quite a nice demonstration of an API using Decoder/Decodable.

My thoughts are that at some point it might become more easy to just change your identity.

Could "'" count as type-parameter sigil for lifetimes? It could at least look like a sigil on a first look.

If it is just for a first try to experiment with structuring those kinds of application, or if your needs aren't even that complicated, it can even be quite close to trivial sometimes. But it's hard to know what is out there, and

That is true, and unfortunately I have used Python only sparingly until now, and have no experience using PyGtk at all. I took a quick look at PyGObject[0] (unsure if that is what one would actually use for this), and the most helpful part
