I've wanted something like this myself. I dislike using `--open`
because I tend to move up to re-run my `cargo doc` run but then have to
edit it to remove `--open`.
Also makes it annoying when opening docs when `cargo doc` is wrapped by
a tool like `make`.
This was previously attempted in #5592:
- Unlike the request in #5562, this aligns with #5592 in always printing
rather than using a flag as this seems generally useful
- Unlike #5592, this prints as an alternative to "Opening" to keep
things light
- Unlike #5592, this prints afterwards as the link is only valid then
Fixes#5562
When running `cargo doc -Zrustdoc-scrape-example`, it performs
additional type checks that a plain old `cargo doc` doesn't.
That leads to some extra failure when adopting scrape-example for docs.rs.
In de34d60 we introduced `unit_can_fail_for_docscraping` in order to
make `-Zrustdoc-scrape-example` not fail whenever `cargo doc` builds.
Build script executions were accidentally included in the list of
fallible units. A plain `cargo doc` does fail when a build script
fails. `-Zrustdoc-scrape-example` should follow that.
