syncbuf VS cacao

I was trying to do something similar a little while back and ended up writing the Synclist type in Syncbuf. This has the tradeoff that the elements are spread across non-contiguous chunks, so it can't be sliced. But it has the advantage of being able to contain any type, memory usage is monotonic, and "reallocation" is much cheaper since nothing is copied.

Since you asked, my little project in this area has been Syncbuf: https://github.com/bplevin36/syncbuf. It has 2 lock-free concurrent buffer types that are low-overhead by being append-only.

I was writing a toy virtual machine when I realized that in order to make it multi-threaded, it would be very helpful to maintain a global symbol table that allowed adding new symbols without invalidating references to old ones. No such thing appeared to exist yet, so I wrote it: https://github.com/bplevin36/syncbuf

This is really specific, but for this point in the article:

> There’s a long guide on Embedding a Command-Line Tool in a Sandboxed App, so I followed that, and then slowly, painfully, factored Xcode out of it, so that I wouldn’t have to figure out how to get a 10GB Xcode install onto the CI machine (remember, you need to be signed in to an Apple ID to download Xcode, and there’s no way to do it from the command-line).

You could actually solve this with Rust and no Xcode whatsoever. cacao [1] and cargo-bundle [2] will produce an app bundle you could sign/notarize/distribute without needing to ever open Xcode.

I've had basic animation support in cacao for about a year now, but I don't think anybody even realizes it.

But I will reiterate what I say on many posts like these, which is that it would be even cooler if we could stop having a million projects reinvent this wheel - and I say this as someone who wrote a large Rust library that is backed by ObjC. madsmtm has an ongoing effort to put together a best in class ObjC Rust wrapper, which would be great to see even more support for.

MacOS; I have to call the AppKit API. I can use a library like this which offers Rust bindings for AppKit - otherwise I can write my own maybe?

Yes, you can: https://github.com/ryanmcgrath/cacao
