How to create a message box in any situation using rust code and dynamically execute different task callbacks.

What kind of entities do you want to have communicating? Is this in-porcess or inter-process?

For in-process (some parts of your program sending messages to other parts of your program) you might be able to get away with a simple mpsc channel -- at least in the simple case. There are other crates out there that support more complex use-cases if that is necessary.

If you are thinking about processes asking other processes to do something on their behalf, you might want to look into something that like the zbus crate -- at least on Linux. On Android you might look into intends, I can not think of the names of similar mechanismns on Mac and Windows right now though:-)
