Enum as int

Hi,

I’m trying to do a RegisterType for an enum type to convert it into an integer before saving it… mainly to save on space. Holding 50k+ rows with a lengthy string value for an enum seems like a bit of a waste to me. It appears to be getting ignored, though. Any ideas? Maybe I’m missing something really simple but I’m not sure what.

Thanks!

enum SomeType
{
   SOME_SUPER_LONG_ENUM_NAME,
   MAYBE_A_SHORTER_NAME,
}

BsonMapper.Global.RegisterType<SomeType>(
    serialize: (s) => ((int)s).ToString(),
    deserialize: (bson) => {
        return (SomeType)Enum.Parse(typeof(SomeType), bson);
    }
);

@darcome This feature is avaliable in LiteDB v5. If you’re using the global mapper, you can configure it to treat enums as ints with the following command:

BsonMapper.Global.EnumAsInteger = true;

Thanks for this! It’s a great starting point. Might be good to note on the wiki too, might be something others might be interested in doing as well.

Much appreciated!
