# Build the Rust toolchain for other tasks:
#
# - The "Rust toolchain" includes all targets/components listed in our `rust-toolchain` file
# - It also includes some targets needed for cross-compilation
# - run-task from taskgraph handles uploading files from UPLOAD_DIR to the public artifacts directory at the end of the task
# - run-task also handles downloading and untaring those artifacts to the fetches directory at the start of other tasks (if `rust` is included in `fetches:toolchain`)
# - `setup-fetched-rust-toolchain.sh` handles copying the files to the correct directories
