  # There is currently no platform mandate to adopt the unused_results lint and it's opt-in for
  # developers that want to use it. See https://fxbug.dev/42153043 for more context.
  #
  # To adopt the lint, add the following to your rust target:
  #   configs -= ["//build/config/rust/lints:allow_unused_results"]
  # The visibility list below can be used to enforce the list on certain areas of the tree while
  # we evaluate wider adoption.

  # To update this list run:
  # $ scripts/gn/gen_visibility_globs.py \
  #    --all=//build/config/rust/lints:deny_unused_results \
  #    --allow=//build/config/rust/lints:allow_unused_results \
  #    --ignore-suffix=_rust  # FIDL bindings use the _rust suffix
