Clients are classes that provide interfaces for requesting and retrieving data usually from remote server.
All the clients are asynchronous. In other words, a request suspends the current engine::Task and other coroutines are processed on the task processor. The suspended task resumes execution on the task processor after the data was retrieved.
It is a common practice to return references or smart pointers to clients from a component. In such cases:
