I tried to workaround lack of `AsRef` provided by `Field`.
Of course, rust won't allow me to just add `impl AsRef<Field> for Field` in
downstream project, so I tried to get away with my own trait as a replacement
for `AsRef`
```rust
// workaround for the fact that Field does not implement AsRef<Field>
trait AsFieldRef {
fn as_ref(&self) -> &Field;
}
impl AsFieldRef for Field {
fn as_ref(&self) -> &Field {
self
}
}
impl<T> AsFieldRef for T
where
T: AsRef<Field>,
{
fn as_ref(&self) -> &Field {
self.as_ref()
}
}
```
Unfortunately, this won't work either. Rust reports duplicate implementation
because upstream may add `impl AsRef<Field> for Field` in the future.
