The shit being sold in the file manager is... space in the cloud for your files. Which is managed by the file manager.

Right- error_chain is just a bit too much magic for me compared to what #[derive(From)] would do.

You can definitely reuse other library's error types. I often do that while prototyping. The benefit of lib-specific error types, though, is that they can be far more specific.

I would love a `#[derive(From)]` for newtype structs and enum variants. Would bring Rust error handling back below Java in boilerplate levels. :)

By manually deciding when to `git commit` in the first place, you're already losing some history. Nobody argues to keep the history of every keystroke, so clearly there is some point in between that and "no history" that is u

> Copy one less than the number you told it, so it would have room to append a NULL? Yep. Or perhaps return an error.

by Rusky 10y ago
I'm well aware of that. Safe Rust, however, allows you to put that pointer in an Rc cycle, or call mem::forget on it, etc.

Rust doesn't guarantee no memory leaks any more than C++.

"Systems language" usually refers to lower-level programming. For example: an OS kernel or its drivers where you're poking at hardware and need control over memory layout, a library to be called from many other languages that

Rust's + implementation consumes the String on the left, so the default behavior doesn't do any allocation unless the string needs more capacity. This makes it impossible to "get it wrong" in the way you seem to be suspe

> Why are fundamental things like resource allocation at least not standardised in the kernel? They are. The slab allocator mentioned in the article is one part of that. The problem here was not that allocation is ad hoc, but that the au

The free list can be stored almost entirely within the free buckets, giving it a constant cost in memory you can't allocate.

Rust does the inverse- it doesn't extend the lifetime of the input data, it restricts the lifetime of the output struct.

This... isn't cloud. It's a server that runs locally, to implement the functionality of an IDE in a way that multiple editors can share.

You can't always swap. For example, you may want to use a movable but non-copyable type to keep un-aliased access to a single resource (see linear/affine types) and the compiler treating the move source as dead is useful there. Or

You can get those benefits without the complexity of C++ if you're willing to break with the past (and as for the newer features, it's possible C++ could have implemented them more straightforwardly, though maybe they were already

Your analogy doesn't sound right to me- there's nothing about wasm that would make it slow to manipulate the DOM, while there is plenty about Javascript that makes it slow to process images. Manipulating the DOM from wasm shouldn&

TypeScript's type system is intentionally unsound in a handful of places- function parameters are bivariant, for example. I believe Flow is at least closer to being sound. I suspect switching from Flow to TypeScript would be relatively

They're often using native code because they have much stricter performance requirements, which means they have everything to gain by doing so. (Though yes, there is an aspect of your last sentence as well)

There are vast gulfs between Steam Greenlight candidates and AAA. Nobody here, least of all me, has claimed that Rust cannot be used for any game at all, nor have they disputed your own experiences. Grow up.

Good thing nobody's claiming otherwise, then. Quit trolling (or, on the off chance you're sincere, learn some basic logic).

I honestly don't know how fundamental an issue it is. I suspect the console vendors and engine/library developers would all have to be on board at some level. For some idea of the timeline- most consoles transitioned from assembly

It's not. There's a reason Mozilla is pushing Servo.

They seem to be aware: ", but it has memory and data race safety, OS threads, and futures, so no problem." However, futures are certainly not boilerplate-free. They destroy your ability to use native control flow the way you can w

This is nonsense. I would love to use Rust in games (I currently work in games) but it's not clear that it would work out. That opinion is shared by game developers far more experienced and prominent than myself. I (and I presume many
