# This file describes an image that is capable of building Flux.

# "Wait," you ask. "What's going on here?" Rather than handling rustup validation
# and verification, we can list the rust container as a prior build stage, and
# then pull in the artifacts we need. The exact rust version used to build libflux
# is specified in rust-toolchain.toml, so always get the latest image.
