>i wanna be lazy and use as many libraries as possible

Sounds like NodeJS is the perfect solution for you.

Buy my NodeJS book:
"How to accomplish very little with a lot and look like you're working."

>>58202892
i love the crate system, it's super easy to use.
the crates index (server that hosts it) just stores the source code that cargo downloads, and lets your computer compile the libraries

>>58202920

>>58202646
I'm writing a symbolic computation library to be used as the backend for a machine learning framework, using arrayfire to support cuda, opencl and cpus all at once. It's breddy gud.

>>58202892
Some are shit (basically ignore anything that's version=0.1.0, typically it's literally just a pass-test and no actual code), some are just C bindings, but those that fit neither category actually have surprisingly good quality in my experience, compared to python or C.

>>58203584

Not yet, shit's too early. I'm doing this entirely in the odd offtime I get. Right now I have working partial derivatives for dot product and addition between arbitrary, up to 4D, tensors (and of course the forward, and utility ops like summing over the entire tensor, creating a constant tensor that's "like" another tensor as an op, and transpose), a system that allows running optimization passes over the graph when that's implemented (far future), and an architecture that makes it fairly easy to add new ops.

I have to write tests and benchmarks, then add the core ops (sub, div, sum across axis, mean, exp, pow, elemwise mul, and conv, should take less than an hour to get them all in but tests will take longer), then I can publish.

>>58203857
Most of those are a single function, like Node.js, since that's the culture all of Rust's users are coming from. All 300 of them.

>>58203948
hopefully lots of that shit consolidates later into a few bigger packages so it doesn't turn into the shitshow that node/npm is

If the 2017 roadmap for Rust pans out, I think it will be the year Rust starts seeing real mainstream traction.

Rust should have a lower learning curve
Rust should have a pleasant edit-compile-debug cycle
Rust should provide a solid, but basic IDE experience
Rust should provide easy access to high quality crates
Rust should be well-equipped for writing robust, high-scale servers
Rust should have 1.0-level crates for essential tasks
Rust should integrate easily into large build systems
Rust's community should provide mentoring at all levels

>> tfw nothing about async libs
>> tfw futures and tokio aren't out yet
Personally I'm looking forward to `tokio` and `futures` being released and then becoming a standard for async. Having an async standard at least partially would be a game changer.

>>58206922
That should fall under "writing robust, high-scale servers"

I'm having such a hard time wraping my head around futures + tokio. Looking forward to the 0.1 release with updated docs

>>58206958
The futures and tokio libs are still very much confusing to me as well. I really itch for https://github.com/rust-lang/rfcs/pull/1522 to be resolved so we can just write `impl Error/Iterator/Future` everywhere.

>>58202845
I do. However it's not feasible at my work as we target embedded linux. Adding rust stdlib to firmwares would be unnecessarily big probably.

So no HKT then, oh well.

>what is libcore

I like the idea of Rust but there's no way I could ever handle that syntax. Not to mention modern Mozilla is something I worry about, they're becoming notorious for ruining their own projects.

>>58207908
The syntax is pretty much lifted straight from C++ except without the unparsability. It's pretty clear that rust is handled by a team completely separate from the rest of mozilla projects on account of the fact it's actually good as is (mozilla is not really known for ruining their projects, it's known for semi-recently having gutted themselves of all competent people to replace them with sjw feminazis).

>>58207908
This. What were they thinking? Did they just make everything backwards and weird so it would look "unique?"

>>58208061
The Rust team also got replaced with SJW feminazis.

>>58208180
[citation needed]
all I see are that the public relations team is the same as usual.

>>58208082
Rust is based in ML. However it would be a lot more constructive if you gave specific samples on what syntax you find weird.

Stating something is weird without specific complaints simply means: "it doesn't look like my favorite PL"

How do you explain Rust being slower than Go in real world usage?

>>58211382
Well how do you explain Rust being faster than Go in real world usage?

>>58207908
I hear a lot of people say this, but I haven't heard any actual cases of the syntax being that much different than from C (execpt lifetimes of course). I already drank the kool-aid, so could you elaborate on what you don't like about the syntax?

>>58211751
>let instead of auto
>fn foo() -> bar instead of bar foo()
>if true {} instead of if (true);
>match instead of switch
>stupid punctuation everywhere
>no ternary operator
>no C-style for loop
I don't see how anyone can learn this garbage.

>>58211751
It looks closer to C++ than C to me, except even more verbose and the symbol choices are even weirder. Some things just seem different for no reason too, like the keyword "match". I haven't seen a real non contrived Rust program in a while though so I can't remember anything more specific. For what it's worth I don't think the C++ syntax is great either, straight C is more or less alright by me.

>>58211809
An attempt to justify some of those design decissions.

>let instead of auto
let signifies the start of a variable decleration, not a type; having auto, imo, would be stranger to read. If you want to annotate a type: let x: i32 = 3;
>fn foo() -> bar instead of bar foo()
I think this might have been to directly address the most vexxing prase. Or just lifted straight from ML.
>if true {} instead of if (true);
You can use parens around the condition, but the compiler will warn. Also braces were probably required to prevent the goto bug in Apple's crypto
>match instead of switch
I think this was because this is more for pattern matching, than just a glorified if/else. People may have been confused if coming from C and they expected switch to behave like C's switch.
>stupid punctuation everywhere
Only out-of-place punctuation I can think of is ! in macros like println!("hello world")
>no ternary operator
This does bother me too, but the common suggestion is writing if some_cond { foo } else { bar }. Definitely not as clean as ternary though
>no C-style for loop
Would be nice if rangees actually covered all cases, but if you just want to iterate ints you can get pretty far with just for i in (0..10).step_by(2) { ... }

>>58211809
>I want Rust to make the same poor decisions authors of C made 50 years ago
There is a reason they made a new language and not C++++.
>let instead of auto
Because types are written after identifiers, not before. Rust has no need to follow C-style.
>fn foo() -> bar instead of bar foo()
The same reason.
>if true {} instead of if (true);
How is this even a problem, this is how it should be in the first place.
>match instead of switch
Because it's not a switch, it's a different operation called "match".
>stupid punctuation everywhere
I can't think of anything unusual except for ! for macros. & and * for references is exactly the same as in C, :: for namespaces and <> for generics are taken directly from C++, -> and => are self-explanatory.
>no ternary operator
Because regular if is already an expression.
>no C-style for loop
Because it's too verbose, error-prone, you almost never need it and you can always emulate it, see Python.

>>58213353
The liberals are going to the block. Even if you don't personally want to swing the axe, you'll be pretty inconvenienced when the entire Rust team (and probably half the community) is disappeared overnight. Don't touch the hot potato and you won't get burned.

>>58216580
It looks like an old-style general, not a new-fangled cancer-styled one like all the new kids are doing these days.

the main reason i fail to take rust seriously is because they seem to mostly shill it on 4chan instead of actually making things that are worth a shit with their language.

>>58216728

func main() {
    ch := make(chan struct{}, 1)

1. Critical parts of Node.js are written in C.
2. Node.js uses V8 JIT.
3. The benchmark itself is IO-bound, so it measures not the performance of language/compiler, but the effectiveness of IO multiplexing method used by the server:

>This microbenchmark tests a “hello world” HTTP server by throwing a huge number of concurrent and pipelined requests at it. Since the “work” that the server is doing to process the requests is trivial, the performance is largely a reflection of the basic overhead of the server framework
