Ready(Box<dyn MacResult + 'cx>)
Expansion produced a result (possibly dummy).
Retry(())
Expansion could not produce a result and needs to be retried.
Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
