Are there plans to support suspending `serialize`/...

# serialization

Are there plans to support suspending `serialize`/`deserialize`? I need to make a database/cache call within deserialize to determine which DeserializationStrategy should be used depending on a field value.

I think that it's better to build a cache in memory.

Or simply use blocking code to query the database.

Cache in memory is definitely better but it still seems like an odd thing to do.

What are you actually deserializing?

[benkuly]

I want to deserilize the different PDUs of the Matrix spec. The room version needs to be looked up in a database using the room_id . To circumvent it, I think I try to detect the PDUs room version depending on the presence of the event_id.

For stuff like I'd do two step serialisation. One to get the PDU with JSON then another to deserialise the JSON once I've done the database lookup.

I just asked in the matrix community and it seems, that holding the room versions of the room ids in memory is the usual approach here...

[Dominaezzz]

There's another issue somewhere where the team decided not to support suspending as it would be too expensive for most cases.

Ah fair enough that works. All for the sake of type safety.
