is nonempty.
|
|
|
|
This process uses multiple strategies:
|
|
- It looks for a parameter that matches the return type.
|
|
- It tries synthesizing 'Inhabited' and 'Nonempty' instances for the return type, while making every parameter into a local 'Inhabited' instance.
|
|
- It tries unfolding the return type.
|
|
|
|
If the return type is defined using the 'structure' or 'inductive' command, you can try adding a 'deriving Nonempty' clause to it.
