# We want to exclude the toplevel Cargo.toml, because that needs to be in
# topological order. But cargo sort doesn't support that.
# https://github.com/DevinR528/cargo-sort/issues/38
# for Arti we have 2 Cargo.toml files that should not follow lexical ordering and need topological ordering
# ../Cargo.toml - toplevel topological sort improves compilation times
# ../crates/arti/Cargo.toml - the main project crate, also needs topological sort
# this means this script will encounter errors twice
# toplevel - will return error about unsorted dependencies in cwd (hence cwd() trickery because forks and branches will have non-arti names in CI)
# the arti crate - this will result the unsorted deps in arti errors
# those two errors are counted towards omission in this script
# So instead, we sed its output. Urgh.
