# NOTE: Cargo is self-hosted, so you need cargo to build cargo (ugh).
#   The bootstrap static cargo has been cross-compiled on GNU system using
#   prebuilt cargo downloaded from the upstream.
# 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!
# FIXME: There's no Cargo.lock in the cargo's repository anymore! According to
#   the upstream, Cargo should be always built together with Rust... For now we
#   at least include Cargo.lock generated locally as a side effect of running
#   `cargo build` for particular $pkgver to ensure basic reproducibility.
