# TEMPLATES

# this step uses cargo-sweep to clean up unneeded cruft that accumulates over time in the target dir. cargo clean is
# not used because it simply rm -rf's the entire target directory (and thus prevents build caching). i would really like
# to either replace this with a bash script, or to install cargo-sweep as a binary instead of building it from source
# like this. i'd also like to add a step that checks to see whether the target dir exists, and exits early if not.

# this builds a "base" version of fif with default features enabled. this is done separately from the main build step
# for the purposes of caching - by building once *before* executing the parallel cargo-build step, we ensure that
# cargo-build can reuse some cached stuff, rather than building from scratch every time.
