# TODO: cargo workspace builds are problematic for us since they take the union
# of the features for a crate from all crates in the workspace: even for leaf
# crates on the dependency graph (i.e. if my workspace contains A, B, and Z
# with Z having two incompatible features, a and b where A requires a and B
# requires b, when a workspace build is run Z will be built with a and b — even
# though A does not depend on B and vice versa).
#
# So, we should perhaps switch to having the full test just build and test each
# crate in the workspace separately. Or we should do away with this workflow
# entirely.
#
# Update this has been resolved for now, but we're playing an increasingly
# precarious game here..

# TODO: feature combinations (for now it's fine since we don't have any real

# Bench, if that ever becomes necessary.
# TODO: it is now necessary!
# So, we'll have a bench thing for PRs that's just `criterion-compare-action`
# But then we'll also have a thing that, for each push:
#   - runs the benchmarks/generates the reports
#   - uses critcomp to make the json file
#   - uploads both to the gh-pages branch under benches/<branch name>/<commit hash>
#      + also adds the corresponding entry on the index page
