> And it's not like you are going to get a huge performance benefit using Rust or C++ over assembly script. Or do they? Unlike Assembly Script, Rust and C++ use LLVM, which is a lot better at optimizing than binaryen.

If those terms mean anything to you: const is an rvalue, static is an lvalue.

You can always just do let no_async = block_on(something_async);

You apparently can "opt out of public code" now. I didn't find an explanation for whether that properly limits it to permissive licenses though. Update: It seems like they check whether the code it emits matches the training

You can opt out of that.

You can write libraries against alloc on stable, but not any executables, because executables not using std need to specify the alloc_error_handler, which you can't do on stable yet: https://github.com/rust-lang/ru

That's not all it does. It "breaks" to the nearest "try" barrier. It's basically the desugaring of the Err branch in the ? operator, that you can't currently express yourself. It's mostly relevant for

You can compile the C code to WASM and then compile the WASM to safe Rust (I wrote a prototype for this and it works). Though as with all WASM, it protects the environment from the C code, but the C code can still corrupt its own WASM memor

While I agree that Rust changed a lot, it was mostly fixing edge cases (like borrow checker limitations or associated types not being allowed to have generics) or obvious missing features in the language (const fn, const generics, async awa

One thing that is stable is marking a function as cold which usually has the effect of marking the calling basic block as unlikely.

One issue I've noticed is that indexing into a T[] array where T can't be undefined, results in the expression to be of type T, not T | undefined, despite an out of bounds index evaluating to undefined. I believe I've seen th

This was supposedly fixed by at least Safari 14.1 (or earlier).

Well arrays never allocate in the first place, but you'd need some sort of specialized iterator api that either: - Handles the iterator not being the same size as the array you want to collect the iterator into and turns it into some s

Funnily enough I just used Copilot to write a reasonably huge PR (it did like 95% of the work), which was indeed mostly a copy paste job (the whole library is a SIMD library with lots of similarities between the different types and operatio

The equivalent list for Windows 10 is missing many CPUs that run Windows 10 just fine... so yeah I don't think this list means anything for the actual consumer.

WASM still needs IndexedDB (or other storage) to store data in the browser.

There's also an open Pull Request for adding std::array::from_fn which calls the function / closure provided N times to initialize an array. This basically brings the array-init functionality into std. https://github.co

The "was been" certainly is a typo at least.

This is actually planned already. Not sure how far along the implementation and progress to stabilization is though.

rust-analyzer is not a compiler. They plan on sharing a lot of code though.
