# of `portable-atomic` crate must also be set by the final binary crate.
# When using the cfg, note that it is unsafe and enabling it for multicore systems is unsound.
# When using the `critical-section` feature, you need to implement the critical-section
# implementation that sound for your system by implementing an unsafe trait.
