That might indeed be the case, I did not look very closely, but mlua has gotten quite some coverage (and I do like lua quite a bit), so I wanted it mentioned :)

Seems to be missing mlua at least: https://github.com/mlua-rs/mlua

transitive performance benefits

I would have assumed the benchmark suite accounts for that, otherwise the results aren’t quite as meaningfull really. Which ties back you your 2nd senctence: I certainly trust the rust team more than myself on these things :)

only affect very select use cases

I did not read the whole conversation, but sorting seems a very common usecase (not mine, but seems to me a lot of people sort data), so this seems quite a broad improvement to me.

that is already perceived as a pain point

Note though, as is mentioned in the issue, that the survey showed people still prioritize runtime performance over compilation performance in general, so this tradeoff seems warranted.

the total regression is still minor

It’s not unheard of that regressions can be unmade later on, so here’s hoping :)

The post mentioned that the introduction of these new algorithms brings compile-time improvements too, so how should I see this?

I assume you mean the first post of the PR? I’d assume it’s simply outdated (or might not have been true to begin with). See https://github.com/rust-lang/rust/pull/124032#issuecomment-2181789935 for the perf run with this PR, it’s showing quite a bit of regression.

Alas, on the whole the compiler slowed down as a result of this. I think it’s a worthy tradeoff though.

No sarcasm, just an honest suggestion :)

From the Fine Readme:

This project allows you to create games for the Playdate handheld gaming system in Rust lang.

You really should preface every announcement with something like this :)

It’s surprisingly simple: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=f176852c61dcf0c3382f0ac97c26de03 As a side node, asking for a value, and then immediately calling to_string on it seems kinda hiding the allocation. I’d suggest let the user call to_string on it themselves.

(e) Changed it a bit to account for passing None as the third argument.

Did I get it right? The crate lets you directly input data into a typst document from an arbitrary struct?

Well, typst provides those means in itself, this crate just makes it easier to fulfill the necessary trait.

Also out of scope of OP, is typst in anyway capable of typesetting music notation?

I don’t really think so. Music notation is also pretty specific, so I’d look into specialized software for that (although it might be theres a latex package, those things are everywhere ^^).

It’s absolutely awesome. For my use case, it already surpasses latex, but I’m pretty sure that for other usecases there will be a point where latex offers more, at least due to ecosystem support. I for sure made the switch (wrote some personal docs in typst as well), and I’d suggest anybody at least looks into switching, it’s so much better :)

From a dev perspective, it’s also great that this is useable as a lib, instead of having to muck with an external binary (or rather full external latex installation).

I have an app that ultimately renders pdfs via typst. I’m starting to write tests for the output, exporting the documents to png instead and then applying something like https://github.com/kornelski/dssim or so.

(If anyone has experience with that, I’d take any hint I get ;))

Note that this is not only a cli and a (closed source) web editor, but also a library. So it’s possible to embed a full typesetting library in your project, which is awesome. It’s probably not on par with TeX yet, but you can already do an awful lot with it. Scripting it is really much, much easier than, say, LaTeX.

I don’t know, I was just surprised by the short timeframe.

Wow, they’re sort-of-targeting edition 2024. I did not expect this, holding my breath ;)

While funny, this also highlights part of why I like rust’s error handling story so much: You can really just read the happy path and understand what’s going on. The error handling takes up minimal space, yet with one glance you can see that errors are all handled (bubbled up in this case). The usual caveats still apply, of course ;)

Non-tutorial suggestion: I’ve you’re stuck, put a demonstration of your problem on the rust playground, post it here with the question. People in rustland are generally very willing to help out, and the playground is a very helpfull tool for that.

Enums/Structs first, but those 2 are mixed, and any impl for them will be directly after the definition of the type itsef. Free functions last.

Hmm, right. I think it still might be warranted in niche cases, but trying to think of such a case made it pretty protracted in my head… maybe when functions can also be called for side effects, and the into conversion is costly and the caller might not care about the return value?

Note that when you change num to take &self instead, this works out (you also need to mark foo as mutable, of course).
