1//! Some of these objects don't expose enough to accurately report their debug state. In this case
2//! we show as much state as we can. Users can always use `Debug2Format` to get more information,
3//! at the cost of bringing core::fmt into the firmware and doing the layout work on device.
4//!
5//! We generally keep the type parameter trait bounds in case it becomes possible to use this
6//! later, without making a backwards-incompatible change.
