tl;dr
I'll be honest, I only read your title, and I thought, with a name like that, who would like Rust? I just spent nearly $2K last year to get rust dealt with and my car repainted.
Who picked that name anyway? Does "rust" ever have positive connotations?

Well, some things are acquired tastes, I'm sure we can all come up with one in particular. But it's also just to get my head around some very different sorts of concepts, and it does have some very different ideas relative to C++.

Agreed, every language has a purpose Pl1, APL, Fortran, etc.
I use C and C++ a lot for my embedded stuff. I actually looked at rust a while back and didn't spend the effort.

You are kidding, right? C# compiles and runs fine for Linux, iOS, Android, MacOS, and now, WebAssembly. With .NET Core and targeting .NET Standard, cross-platform is a reality.

Oh, sure, but the reality is what is widely available in terms of jobs, not what is technically doable. The vast bulk of .Net jobs are going to be on the Windows front, at least the ones I've seen.
The place where obviously that may (if we are lucky) really change is on the browser with Blazor/WASM. But I'm not much interested in writing browser based code, or writing trivial phone apps either. I'm helping someone with a Blazor based product currently, and it has a lot of promise, or at least as much as anything that runs in a browser and is still fundamentally stuck with HTML/CSS can be. And he is using that combination in hopes of supporting multiple platforms, but only in a browser based context, and the back end is all Windows.

Your concerns about Rust may be justified (I'm not taking sides!) but I noticed two things:
(1) Dean Roddey wrote: But of course Rust may never get beyond the interesting idea phase and get seriously used.
Rust is in serious use right now. There is Rust code shipping in Firefox.
(2) Dean Roddey wrote: And Rust may suffer in other ways from not having any real single driving force.
Rust does have a single corporate backer/driving force: It is Mozilla. Indeed, this is a source of criticism from some quarters since people say that Rust is structured to solve Mozilla's particular issues with C++ in a very large code base.
As for "not a glorified scripting", what do you think of Go or D?

Ok, Mozilla is of course an entity, though a fair bit different from one like Microsoft, it seems to me, having a large part of it being a non-profit foundation, and having a lot of community driven input at least as I understand it.
Given that Firefox is also Mozilla's I wouldn't count that overly heavily in Rust's favor as being in real use. They'd probably look the other way far more than another company would in terms of issues and such. I mean it obviously proves it's doable, but from what I'm reading once you get beyond the language to practical issues of packaging and large development structures and such that it still is pretty raw. Though sometimes it's hard to tell what info is really accurate and/or up to date.
Not yet looked at Go or D, since I just have had the impression that there wouldn't maybe be much of a career path improvement in those directions, though I could be wrong on that. Given my interest in large scale frameworks and such I'd definitely want something that has the same breadth as C++, or close thereto. I'm not sure Go fits that description?

I should say before I comment further that I'm not a fan of Rust as such but it does look like it has a future to me.

Other way round, surely. I.e. If there's a problem then they can and will fix it.
Additionally, Firefox is a heavyweight code base and is surely as real as it gets.

With Go being backed by Google I think it might well have a massive future.
Sadly D's future does seem more questionable. I think it has suffered due to not having big time corporate backing like MS, Google, Apple or even Mozilla (in this context at least).
I don't claim to be a Go expert but it certainly does seem, as I understand it, to be intended to have the "same breadth as C++" but of course it could depend on what that means in practice for you.

I dunno. I think that, if you really want to use something, you'll overlook a lot of 'beauty marks'. I imagine that they would do that because they want to use it. Obviously they would fix anything causes bugs, but things that might make it less practical for real use (which may be things well outside the language itself such as packaging, build schemes, tools integration, whatever, and obviously ongoing changes to the language) they might well very much give the benefit of the doubt that it will get taken care of and put in the work to get around it, whereas another company wouldn't commit until after those things are taken care of in most cases because they can't afford to do otherwise.
There's a huge chicken and egg thing all around. I wouldn't commit to learning a language like Go or Rust (meaning seriously, not just poking around) unless I knew there was a substantial likelihood it would benefit me career-wise (which translates to there are lots of jobs doing it) but there won't likely be lots of jobs doing it unless companies believe that there is a large talent pool out there to draw from.)
And of course with Go there's the problem that Google drops projects right and left all the time and a lot of people wouldn't want to commit themselves to anything that fundamentally if it comes from Google because they could get seriously screwed. And I imagine a fair number of folks don't want to contribute any more to Google's hold on the industry (and the world.)

> One I ran into tonight is that there's no such thing as a constructor
The problem you're describing is not the absence of a constructor but the absence of function overloading. Rust doesn't have constructors, because there's no need for a constructor as a separate function. That said, rust differentiates between function identifiers and struct identifiers, so you can create a function with the same name as the struct and call it. It will look just like a constructor in C++.
The reason rust doesn't have overloading is explained here.

But, either way, it lacks the incredibly obviously important means to do convenient and controlled initialization with various parameter combinations in a standardized way. That seems crazy-like to me. It doesn't seem to me that making an exception on overloading just for ctors would be such a huge compromise and would get rid of a raft of repeated silliness in every program.

I've been programming in rust since 2016. The number of times I thought "man, having function overloading would be really nice" can be counted on the fingers of one hand. If you have a case where you need overloading and the code looks more readable with overloading, you're welcome to discuss it on the language design forum.
|

Well, it wasn't about actual overloading, but construction. Object (or structure) initialization in Rust seems very weak to me, for the reasons I enumerated in my original post. Obviously we can live without overloading in general. My own CML language doesn't support it in general. But it does support it for constructors, for the same obvious reason that we want a consistent, formalized means for controlled initialization of data structures with variable parameter sets, not a somewhat ad hoc set of mechanisms that are either convenient but unsafe or safe but inconvenient.

BTW, while I'm whining... Who made the choice not to use an explicit return statement? That seems particularly non-optimal. There's absolutely no visual difference between the last statement falling out the bottom and an incomplete line of code just from looking at it. I mean readability is far more important than saving a few characters.

Things have moved on quite a bit since you wrote this. It has become a thing, with most of Big Tech backing it and now using it a lot.
Even Google with Go sees a need for it. They will be using it in Android, for example.

Actually I've dug into it quite a lot since then, and the more I use it the more I'm gravitating away from it. I get it of course. The memory safety is a huge, almost overriding benefit. But I just hope that these ideas get incorporated into a language I like better on the whole.

Was watching news tonight (I know - filthy habit) and heard that someone decided that the universe was several billion years younger than was previously thought. When I was younger this would have been interesting in a 'wow science is awesome' sort of way, but now I just thought "So what? Does it help make my car payment, or pay the mortgage, or improve my life?" And I was saddened to reply (to myself) "Nope".
This makes me sad

It's just a side effect from the incessant streams of bullsh1t that spew forth from the "science" known as astronomy.
Almost every press release from every astronomer could be replaced with wither the word "bullsh1t" or the word "wolf".
It's impossible to get excited about a "great new discovery" when you know it's probably just a new great big lie.
