coverage: 84.95%. remained the same
when pulling 554e607 on update_ci_pipeline
into 0f6a7c2 on main.

I've also replaced the current coverage tool (grcov) with tarpaulin, although I am unsure if this should be kept in.

With grcov, I had some issues with excluding directories. I got an obscure missing file issue when adding --ignore /* as was previously done by the actions-rs version of grcov, but not adding it causes some non-code files to be included (no idea where the coverage values for those come from?!?), see https://coveralls.io/builds/69151273.

cargo tarpaulin however seems to have a bunch of false negatives and/or positives, see https://coveralls.io/builds/69151472/source?filename=src%2Ftoken%2Fcose%2Fmaced%2Fmod.rs#L208 for instance.

Considering that the coverage numbers seem to be vastly different when comparing the current state of main with the one of this PR, at least one of the two different coverage reporting tools seems to be very off.

Any opinions on this (pinging @falko17)?

Hm, we should investigate more deeply why these numbers are so different (67% vs. 85%, if I interpret this correctly). Given the extensive tests we have in place, I trust the 85% number more, but this could also be too optimistic—we need to take a deeper look into it before we decide on which tool to use.

As tarpaulin seems to have a number of false negatives, I have switched back to grcov and fixed the aforementioned issues.

The line coverage calculation now seems to be fine, the coverage percentage being lower is due to the branch coverage being aggregated with the line coverage, see https://coveralls.io/jobs/149319128.

I don't think branch coverage is necessary/useful for this project, so I've disabled the aggregation for now so the number is easier to interpret (and higher :D).
