hello, i am an absolute newbie to rust. is rust an object-oriented programming language? i ask because i detest 'oo', and am looking for something better than c. thanks, ~mayuresh ___ Rust-dev mailing list Rust-dev@mozilla.org

[rust-dev] Cross-compilation with plugins is effectively dead?

I have some concerns related to https://github.com/rust-lang/rust/issues/18699 and I'd like to get some advice from the team. Support for cross-compiling code with plugins was broken for a few months now for anything but linux. Finally it seems to be broken for linux as well halting all our

Ok, with wycats point me out to the issue and got it working. You can see the diff here https://gist.github.com/spastorino/a286f296a850b8ea5d0f/revisions PR to rustbyexample sent ... https://github.com/rust-lang/rust-by-example/pull/374 On Thu, Jan 8, 2015 at 2:24 PM, Santiago Pastorino

[rust-dev] rustbyexample.com's failing example due to changes in nightly

Hi everyone, I was looking at rustbyexample and found that some examples are not working using the latest nighly Rust compiler. I've fixed one example https://github.com/rust-lang/rust-by-example/pull/371 already merged and now was looking at this one http://rustbyexample.com/bounds.html. I

Re: [rust-dev] About const

We have two types of floats, there is a Pi of both precision levels. I don't think it's anything more than that. You should be able to cast between the two, but that's it I guess. Rust tries to give explicit control over such things. There is a Float trait (might have been renamed) if you want to

[rust-dev] About const

Dear Rust Developers, here is another ignorant question so feel free to ignore. When reading the guide I came across std::f64::consts::PI” for pi. Now I was wondering why there are separate constants defined for 32 and 64 bit floats and how this will work with generics. Do you always have to

Re: [rust-dev] Declaring the API unsafe while keeping the internal safety checks

Well, strictly speaking it *is* memory safety, as it all gets down to an unsafe volatile store. Although I think I extend the 'unsafety' a bit by considering code that can cause CPU to halt as unsafe too. On Fri, Jan 2, 2015 at 2:11 AM, Kevin McGuire kmcg3...@gmail.com wrote: Yes unsafe is

Re: [rust-dev] Problems cross-compiling to ARM9

FWIW, we're just disabling segmented stack in zinc for now exactly because of the same problem. I have a patch for llvm but I didn't really push it upstream hard enough. On Tue, Dec 30, 2014 at 11:23 AM, Valerii Hiora valerii.hi...@gmail.com wrote: Hi Tomi, Anyone have any idea if that's a

[rust-dev] Why .iter() for looping over arrays

Dear Rust developers, I have just started using rust so this is obviously a stupid question but I was wondering why .iter() is needed when looping over the elements of an array? In the following example: let a = [1i, 2i, 3i]; for e in a.iter() { println!({}, e); } why

Re: [rust-dev] Problems cross-compiling to ARM9

- Rust - can be relatively easy fixed by providing (or patching) a target and marking it as a target which doesn't support segmented stacks, see example [1] - LLVM - as I remember some time ago LLVM generated a function prologue which uses the same instruction for any ARM device The

Re: [rust-dev] Problems cross-compiling to ARM9

So far my best guess is that the problem is the Assmebly line mrc 15, 0, r4, cr13, cr0, {3} in main, which means that it's trying to read from coprocessor 15, register 13, part 3. According to http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360e/CACEAIHG.html that's a thread

Re: [rust-dev] Problems cross-compiling to ARM9

Hi Tomi, Anyone have any idea if that's a larger problem, or simply something nobody has written the small handcoded ASMs needed for ARMv5 or v4? If latter, I might be able to wrap my head around this. The problem you've got is related to segmented stack support. It need fix on 2 levels:
