# Note: Cargo is self-hosted, so you need cargo to build cargo (ugh).
# XXX: Cargo depends on many crates (Rust packages) and currently downloads
#   them itself in the build phase. This quite violates our policy. However,
#   unlike some other package managers, Cargo does not download arbitrary
#   packages from the Internet without any verification. The source tarball
#   includes file Cargo.lock that contains complete dependency tree with exact
#   version and checksum for each crate . With --locked we force cargo to
#   adhere to this file and verify checksums. So it provides the same
#   guarantees as abuild. That said, for now it's exception only for cargo
#   package and should not be applied to other rust packages!
