# Proxy dependencies
#
# Fetches all required rust dependencies and caches library artifacts. All Conduit sources
# are omitted from the resulting image so that artifacts may be built from source over
# this image.
#
# When this file is changed, you must run `bin/update-go-deps-shas`.

# Compile the application to ensure we've obtained all build dependencies and that they
# compile.
