Hi allI am trying to implement Option<T> type in FPC. type generic TOption<T> = record case IsSome:boolean of true: ( some: T ); false: (); end; However fpc just emits errors: Error: Type parameters may require initialization/finalization - cannot be used in variant records
You simply can't use managed types in a variant clause and as T could be a managed type the compiler does not allow it.
Could anybody suggest some sane workaround for the problem?
Use Nullable.TNullable<T>. Regards, Sven _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
