Cargo generates examples in two files: one is the example name, and the other is suffixed with a fingerprint. these extra binaries do not need to be installed, so check for this condition in the install step.

Thanks for the PR! It'd be simpler and clearer to exclude those files with a bash regex match instead:

| if [[ -f "$example" && -x "$example" && ! "$example" =~ '-[[:xdigit:]]{16}$' ]]; then |

i did some experimenting with your change here, and unfortunately it did not filter as i expected. Looking through the documentation i found this:
https://docs.yoctoproject.org/bitbake/2.4/bitbake-user-manual/bitbake-user-manual-metadata.html#shell-functions
that section includes the sentence You should not use Bash-specific script (bashisms).
I do agree that this should be simplified, and i'm exploring some other options
This filters in the original line, and also checks to see that the un-suffixed version of the file exists. conditional shortcutting should keep this from being too expensive
