# Enable shared bus implementations using `std::sync::Mutex`
std = ["alloc"]
# Use `portable-atomic` to enable `atomic-device` on devices without native atomic CAS
#
# `portable-atomic` emulates atomic CAS functionality, allowing `embedded-hal-bus` to use `atomic-device` on hardware
# that does not natively support atomic CAS. If you enable this, you must also add `portable-atomic` to your crate with
# a feature flag such as `unsafe-assume-single-core` or `critical-section` to choose how atomic CAS is implemented.
# See https://docs.rs/portable-atomic/1.7.0/portable_atomic/#optional-features for more info.

# Enable `embedded-hal-async` support.
