sccache VS proc-macro-workshop

Worth noting that the first commit in sccache git repository was in 2014 (https://github.com/mozilla/sccache/commit/115016e0a83b290dc2...). So I suppose that what "happened" happened waay back.

If you have lots of shared dependencies, maybe try sccache?

I'm going to set up sccache [0] to use it tomorrow. We use MSVC, so EFS is off the cards.

I think the primary benefit of pre-built procmacros will be for build servers which don't use a persistent cache (like sccache), since they have to compile all dependencies every time. But IMO improved support for persistent caches would be a better investment compared to adding support for pre-built procmacros.

Checkout https://github.com/mozilla/sccache

https://github.com/mozilla/sccache is another option which addresses the use cases of both icecream and ccache (and also supports Rust, and cloud storage of artifacts, if those are useful for you)

That being said a compilation cache, eg the de-facto standard for Rust: sccache (https://github.com/mozilla/sccache) will help to compile and store some of the build artifacts centralized - still for each crate version + build profile (RUSTFLAGS) combination.

That's definitely not my experience. Never had any issue running Rust on Windows. You just download and run rustup-init.exe, then updating is simply a matter of rustup update. Documentation generation is built in (cargo doc) and just a case of annotating code with triple-/ markdown comments and then running that command. sccache works fine for me (just need to set RUSTC_WRAPPER=/path/to/sccache). And the error messages from rustc are by far the best of any compiler I've used. Not sure how they're unhelpful, they tend to explain step-by-step what the problem is and how to fix it.

Tangentially, the proc macro workshop walks through building a derive macro implementing a builder pattern. From experience, I can tell I couldn't ever write proc macros just by reading the manual, going through it is really helpful https://github.com/dtolnay/proc-macro-workshop/blob/master/README.md

I am working on the proc macro workshop and am a little stuck on the builder portion of the workshop. Step 08-unrecognized-attributes wants you to handle the car where the field modifier has a misspelled portion (eac instead of each)

I would very much second the suggestion to do David Tolnay’s Proc Macro Workshop if you want to start understanding how to write them. I’d been writing Rust for years but always kind of avoided proc macros.

When I had a need for them, I went through only the first section of the workshop and everything clicked. You can just do the derive macro section and all the strange and scary-looking macro syntax will make sense. I realized that there is only a bit of extra syntax but it’s used very often so it can seem a little overwhelming when reading macro code.

Another good one imo is the proc-macro-workshop.

Don't be afraid of proc macros and derive macros, they rule. Study the basic examples. Crates like darling and resources like David Tolnay's workshop will help. Write derives for your simpler traits and impress your colleagues.

Regarding 4, I think that macros are an interesting intermediate/advanced topic. I personally loved the material from https://github.com/dtolnay/proc-macro-workshop

It took me a while to get anything done. My mistake : I came accross the procedural macros workshop several times, and every time I dismissed it, thinking - meh I'll just hack together exactly what I need and move on. Then finally I figured there is no way around it. The builder exercise sounds boring but it covers the topic pretty well. And then I went on to the debug one and from there was able to build the proc macro I wanted.
