While going through all the structs in order to add missing `Send`
implementations, it occured to me that it may be a bit confusing if
only this one type has the `Owned` suffix, while the others are also
"owned" but do not carry that suffix.

Not really sure how to resolve this... We could rename the non-owned
`Info` to something like `InfoRef` and turn `InfoOwned` back into
`Info`, but reading `&InfoRef` may be a bit weird?

Alternatively, we could rename all other structs to add the suffix...
Then, "Owned" would maybe sound confusing - given that no un-owned
variant exists.
Maybe "Box" would be a more suitable suffix in that case - borrowing
from the Box type name [1]?

Any opinions here?
