This post has three important images that you can't see via GitHub review, so I strongly recommend building and viewing it locally:

git clone https://github.com/nnethercote/blog.rust-lang.org/
cd blog.rust-lang.org
git co parallel-rustc
cargo run

Then follow the printed instructions to view the main blog, then follow the link near the top to the the "Inside Rust" blog, then look at the top post.

I have put 2023-11-10 in as a tentative publication date, but that is definitely subject to change.

I'm happy with the post, I think it explains things nicely. Any and all feedback welcome!

Very nice write-up! I almost feel like it's a shame to have this nice writeup on the Inside Rust blog, and not the main one xD But people will find it anyway.

[SparrowLii]

Really nice!

I'm personally in favor of this going on the main blog. I think this is effectively framed as a call to general Rust user audience to test, so it makes sense to put it there.

[nnethercote]

Thanks for all the review comments. I have added a new commit that addresses most of them.

I'm personally in favor of this going on the main blog.

I don't have strong opinions either way, but I do notice that the Inside Rust blog has numerous articles with "nightly" in the title while the main blog has none.

BTW I will do at least one more edit pass this week to tighten up the prose, but I don't expect any content changes.

[nnethercote]

I have done my final edit. I think it's ready to got on Nov 10, modulo possibly any remaining changes to the "Feedback" section.

BTW, I'll be away for the weekend from Friday afternoon onward, Australian time, which is early Friday morning in Europe and Thursday evening in North America. So it might make sense to publish some time today, i.e. in the next 12 hours. That will ensure I'm around for last minute edits, and for the first 20-24 hours of discussion on Reddit, etc. Thoughts?

[nnethercote]

Ok, I think this is ready to publish. @Mark-Simulacrum, are you the right person to approve it?

[Mark-Simulacrum]

Happy to merge if we're ready (looks like still at least one comment thread left)

[Mark-Simulacrum]

Oh, also the post is one day in the future.

[Mark-Simulacrum]

I'll try to bump the date this morning and merge.

the image links are now to inside-rust and for the wrong date, but at least doesn't break them being displayed on the blog
