I tried re-running and appears to have succeeded the second time but this was highly odd:

Not sure what to make of the error since I can't reproduce and no longer have the full build log. Perhaps just look the other way?

How interesting.
You seem to have hit an edge case in my attempt to work around breakage where `--keep-going` combined with a build failure could result in installing two copies of rust with the same version over the top of each other, but would leave the old copy installed (the uninstall action doesn't run until the next depclean).
The error here is that we attempt work around that in postinst, however if we don't find a match for a file (in this case we should find two files that match `/usr/lib/rust/1.80.1/lib/rustlib/i686-unknown-linux-gnu/lib/libcore-*`) we bail out rather than continue removing files.
I can't see a reason for you to have encountered this; libcore is not optional. We generate the list of files in preinst so we know it used to exist. Maybe you had a hash collision? Seems very unlikely but it's the best guess I have right now.
| Code: | $ equery f dev-lang/rust:1.80.1 | grep -i libcore
/usr/lib/rust/1.80.1/lib/rustlib/i686-unknown-linux-gnu/lib/libcore-df5993c644c6a958.rlib
/usr/lib/rust/1.80.1/lib/rustlib/x86_64-unknown-linux-gnu/lib/libcore-ccfb3e0972f09e06.rlib |
I've just noticed that we say rlib when we also check for a few so files; I should update that.
Long term this needs to be fixed in Portage when someone has time to investigate. Related bugs:

As a personal note that might be helpful for others is that I was running --jobs=4 and indeed with --keep-going on my 10 core machine machine with distcc enabled. The first time around it gave up trying to --resume but it was able to finish when restarting emerge from the top.
The actions regarding the -r100 was weird and I think it eventually depcleaned.

If there is interest, I have a full log of a very similar error, but not the exact one. Mine ends with:
| Code: | * Removing old .rlib file /usr/lib/rust/1.81.0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libsysroot-db2bd41680f067c1.rlib
* ERROR: dev-lang/rust-1.81.0-r100::gentoo failed (postinst phase):
* Expected exactly two files matching /usr/lib/rust/1.81.0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libminiz_oxide-\*.rlib, but found 1 |

Were you also using --jobs and --keep-going? Happen to know what was running at the time of failure perhaps?
At least we can probably assume that this is not a hash collision, I don't think hash collisions could happen this frequently?
