# We distinguish the following kinds of builds:
# - native: build for the same target as we compile on
# - web: build for the Web
# - em: build for the Emscripten

# For build time and size optimization we disable debug
# entirely on clippy jobs and reduce it to line-numbers
# only for ones where we run tests.
#
# Additionally, we disable incremental builds entirely
# as our caching system doesn't actually cache our crates.
# It adds overhead to the build and another point of failure.
