 /// This function returns a `Sender` half and a `Receiver` half that can be used as a body type, allowing for efficient streaming of data between tasks. The `Sender` can be cloned to allow sending to the same channel from multiple code locations, making it suitable for multi-producer scenarios. Only one `Receiver` is supported, adhering to the single-consumer principle.
