Function process_metadata 

Source 
pub fn process_metadata<T>(
    value: Result<Option<T>>,
    classify: impl FnOnce(&Error) -> ProcessFailure,
) -> Option<Option<T>>
Expand description

Interpret an optional process query: outer None means vanished; inner None means unknown. Used by adapters before the inventory collector, so unknown metadata keeps its PID.
