So, you can wrap one approach with the other:
```rust
#[cfg(feature = "embedded_hal")]
impl InputPin for Pin {
    type Error = Infallible;

    fn is_high(&self) -> Result<bool, Self::Error> {
        Ok(Pin::is_high(self))
    }

    fn is_low(&self) -> Result<bool, Self::Error> {
        Ok(Pin::is_low(self))
    }
}
```
(Old EH impl there; haven't updated)
