This is a redesign of the feature, with parts pulled from rust-lang#119049 but with a button that looks more like a button and matches the one used on other sidebar pages.

I found the previous design way more obvious. In this case, nothing indicates that:
- There is a sidebar
- The sidebar is not about the content but about files hierarchy
Also I really don't like the appearance when sidebar is opened for the title and close button (that is very much personal taste).
There is a sidebar
Is this about the empty vertical column when the sidebar is closed, or is it about the icon?
I had removed the vertical column because it ate into horizontal screen real estate, which is at a premium since code isn't line wrapped. But if you find that helpful, it could be redesigned to put it back.

icon doesn't seem better about that.

I'm hoping to lean on people's existing familiarity with GitHub.
The fact that this particular icon doesn't seem to have a tooltip in GitHub's design should be criminal, and this PR does include a tooltip for this exact reason. But the icon isn't exactly the same (it's closer to Apple's).

On mobile the vertical column isn't visible and I think the problem is quite limited on desktop. But yes, I think it'd help to make the connection between the button and the sidebar.

Indeed.

And because of this comment, I just realized that this sidebar could be collapsed. I'm not sure if it's bad UI or just me who's very bad at that... 😅

The button doesn't stand out much either in their case, hence why I never paid attention to it.

No problem. I've just pushed a new version of the preview docs and PR with the vertical placeholder column.

Do you think this is because:
- The buttons doesn't look like buttons? GitHub's buttons are pretty similar to ours, and if they don't look like buttons, then we should probably add more shading or otherwise try to improve clickability signifiers.
- The icon is bad? What does a good sidebar icon look like? (hamburger buttons should open a modal slide-out, not toggle a persistent navigation panel)
- This particular button is badly designed for some other reason?

It doesn't look quite right, because the lines are too far apart, and it's not going to be announced by screenreaders as a menu button, since that's not what the symbol means.
This adds a real tooltip and uses a better drawing of the icon.

Much better for when the sidebar is closed. Now my only question is about the mobile version: currently we can open the sidebar wherever we are on the page. With your change, it's not possible anymore. I think to be taken into consideration as some source code pages can be quite huge and if you're at the bottom, it's quite annoying to go back to the top. And also, it makes the sidebar harder to "discover" if you're not already aware of its existence in this case.
Now for when the sidebar is open, I think the title should still be centered and the button remaining on the left side (as currently). You also removed the line which was used as marker to differentiate the "title" and the "content" before. Any reason for that change?
Do you think this is because:
* The buttons doesn't look like buttons? GitHub's buttons are pretty similar to ours, and if they don't look like buttons, then we should probably add more shading or otherwise try to improve clickability signifiers.
I think it would be already a pretty good improvement. I think it's because there is not a strong enough visual marker that I don't notice it.
* The icon is bad? What does a good sidebar icon look like? (hamburger buttons should open a modal slide-out, not toggle a persistent navigation panel)
Not a strong opinion on this one. But in this case, I think we should use the same icon for both mobile and desktop, whichever it is.
* This particular button is badly designed for some other reason?
Since you moved it back inside a "column" on desktop, looks good to me. On mobile I still have worries I described above.

That's odd. What browser are you testing on? The hamburger button is supposed to stick while you scroll, the same way the >
button did.

I prefer left alignment because the docs sidebar does it the same way.

Not really. If you want it, I'll put it in.

I guess it would need to use a hamburger in on both desktop and mobile, then, since the sidebar icon would be wrong (the file browser fills up the entire screen on mobile, but the icon depicts it as only partially filling the screen).

After a force refresh, problem gone. All good there. :)

Depends on the "mode": on mobile, the button is on the left and the title is on the right. There is no equivalent for desktop to compare to unfortunately.

Let's see how it looks with it then. 👍

Sounds good to me.

That's how the top bar looks. I was thinking of the sidebar logo lockup and its headers.
Sounds good to me.
It doesn't sound very good to me, because that icon usually opens a modal instead of toggling a setting.
Backing up and trying to think of a different approach, maybe we should use an icon based on its purpose instead of its mechanics, which is the same across all viewport sizes.

The fact that this particular icon doesn't seem to have a tooltip in GitHub's design should be criminal
Interestingly they do have a tooltip on this exact icon in the PR-diff-view.
The biggest thing I notice with this (and github's similar button) is that it feels wrong to me that it's on the left, the button to close a panel should be in the top-right. But that's likely platform-specific behavior, and I don't think rustdoc has any similar UI anywhere to be self-consistent with (unlike github which uses top-right-close everywhere I can see except this one panel).
🔔 This is now entering its final comment period, as per the review above. 🔔
The final comment period, with a disposition to merge, as per the review above, is now complete.

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request
This is based on the pkgsrc-wip rust180 package, retaining the main pkgsrc changes as best as I could.
Pkgsrc changes:
- Adapt checksums and patches.
- Make this work again on big-endian aarch64 (at least on NetBSD).
- Make the choice of GCC = 12 work for sparc64 by testing options after options.mk is included (which is required...). Makes this work on NetBSD/sparc64 10.0 again.
