# rust_arches: list of architectures where building Rust is supported
#
# Since RPM itself now depends on Rust code (via its GPG backend, rpm-sequoia),
# this list will probably always be a superset of all architectures that are
# supported by Fedora, which is why it is no longer required to set
# "ExclusiveArch: rust_arches" for Rust packages in Fedora.
