# A wrapper around rustc/clippy to set up the correct absolute path for OUT_DIR.
# This has to be done on invocation rather than precalucalted in Soong to
# ensure that RBE calculates its own absolute path rather than inheriting the
# local host absolute path.
#
# The first argument should be the path to rustc/clippy

# Check if $SOONG_RUST_GEN_DIR is set, otherwise don't do anything.
