Context cancellation and timeouts are propagated to the handler.
The client does not wait for the remote handler to finish before returning.
Returning any error will also cancel the stream remotely.

CAREFUL: When utilizing two-way communication, it is important to ensure that the remote handler is not blocked on a send.

* Try to make the title descriptive about what it achieves. If it's a feature, try to describe it, for example `Add support for teleporting` instead of `Create TeleportAdapter class`.
* Do not finish the title with a period (`.`).
* When the PR is for a translation, start with the `🌐` and then `Add {language} translation for` and then the translated file path. For example:
