# Use the portable_atomic crate to support platforms without native atomic operations.
# The `portable_atomic_unsafe_assume_single_core` cfg or `critical-section` feature
# 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.
# See the documentation for the `portable-atomic` crate for more information:
# https://docs.rs/portable-atomic/latest/portable_atomic/#optional-cfg
