Cargo.toml

# A fake Cargo.toml for cargo-raze. This will not work well if you try actually
# running cargo.
#
# cargo-raze generates BUILD files etc for all dependencies listed here and in the workspace
# members. Hand-written BUILD files can then depend on the corresponding targets that they need.
#
# To generate BUILD files from this:
# ```console
# $ bazel run @cargo_raze//:raze -- --manifest-path=$(realpath Cargo.toml) --generate-lockfile
# ```
# To remove unnecessary redundant BUILD files afterwards:
# ```console
# $ bazel run //tools/rust:tweak_cargo_raze_output -- $(readlink -f .)
# ```
#
# # Generated targets
# //third_party/cargo has forwarding targets for the individual crates. Don't
# reference the repositories by name, because those change when they're
# upgraded. If you need to access another target, set `extra_aliased_targets`
# for the crate.
#
# See here for what you can set in the package.metadata.raze sections:
#   https://github.com/google/cargo-raze/blob/main/impl/src/settings.rs
