Is there a possibility to make store fields readonly?

[StarGuardian]

Hello all!

I'm developing an application with uses unidirectional data flow architecture. There is a state machine which gets events from the UI, sends requests to the backend and updates data for the UI. Reactive stores suits this well, but I prefer to have only one point where the state can be modified. As far as I understand reactive stores allow modification anywhere. How can I prevent it? It would be similar to signals which have separate ReadSignal and WriteSignal parts.

To be honest, the main reason there isn't a read/write separation for stores is just the additional duplication/boilerplate of creating additional structs in the library that it would entail.

You can roll your own fairly straightforwardly using the Signal and SignalSetter structs, or creating your own wrapping ReadField and WriteField structs (or whatever) that only implement one or the other of the Read/Write traits by simply passing them through to the underlying store field type.
