Here are a couple of examples of the changes that were made in the two or three years before Rust 1.0 if anyone wants to read more: https://github.com/rust-lang/rfcs/blob/master/text/0230-remo... h

The problem is, Go uses a concurrency model (stackful coroutines/fibers) that was all the rage in the 90s (to the point where the Windows APIs have vestigial support for it) and then got abandoned by everyone except them for reasons th

Ahh, the dynamic linking thing. To some extent, I see that more as "Distros have ossified around the workflows and tooling that is essentially 'a third-party package manager like Conan for C++, but for C'". How do you de

Currently, it has two built-in ones for `cargo new` and `cargo init` (--bin and --lib) and there are third-party tools like `cargo generate` which provide for more, but they haven't accepted anything into the main distribution yet. ht

That's Cargo's by-convention auto-discovery. You can manually specify the same information in Cargo.toml if you prefer to customize it. https://doc.rust-lang.org/cargo/reference/cargo-targets.html...

For one thing, "liable" applies to both civil and criminal law, so equating it to "criminally prosecuted" is definitely wrong.

What you're describing is reminding me of how Itanium tried to bring VLIW to non-embedded spaces and found "make the compiler smart enough to use this well" to be much easier said than done.

Good point. It's probably fundamentally a cost-cutting measure in both cases, where Microsoft just found it cheaper and easier for similar reasons. (eg. Win32 isn't a convenient API, Qt has license fees while Electron does not, Mi

Appealing in theory, but not necessarily attainable in practice. I use Rust to write CPython extensions... it's a well-known fact that GCs are solitary creatures and you're in for a lot of hassle if you want two different GCs to p

Would you mind elaborating? It was removed from the standard library ages ago, but `crossbeam::scope` appears to still be there in the newest release of crossbeam and the git repo.

Honestly, as a consumer of libraries, I much prefer when they're written in Rust (without gratuitous use of `unsafe`) compared to a language which doesn't make you think about these sorts of things as hard.

Rust 1.0 was explicitly intended to be a Minimum Viable Product, containing only the work they felt they couldn't revise later without breaking their API stability promise. As such, they started with the versions of allocating APIs tha

...and I'm saying that Rust is the only language where the benefit of using it for its type system has, for me and so far, outweighed the downsides of having to think about memory management. Java? Pain in the ass with all those non-in

As I understand it, it's because Cyclone's big advantage isn't what made Rust popular. It's that Rust combined a whole lot of attractive features in a single package, of which, memory safety without GC is only one.

They've already responded that their use of "alloc", which is designed more for userspace, is just a temporary thing that they plan to replace before any serious submissions. See also https://github.com/Rust-f

I came to Rust for things like sum types, lack of unexpected null values, monadic error handling (Result<T, E>), and the borrow checker's ability to enable the typestate pattern. ( https://cliffle.com/blog/rus
