Use kotlinx.rpc to exchange events between apps and debugger

[kitakkun]

Recently, kotlinx.rpc was officially released. Though it is still in a Experimental stage, if we can adapt to it, the implementation for communications might become easier than current websocket implementation with Ktor.

The kotlinx.rpc allows us to send or receive flows via value parameters or return value of 'services'.

We can define RPC interface like below:

interface BackInTimeRPC : RPC {
    suspend fun initConnection(sessionId: String?, appEventFlow: Flow<BackInTimeDebugServiceEvent>): Flow<BackInTimeDebuggerEvent>
}
