 `try_push` is ideal for trivial types (like `int` or `float`) or when you already have an existing object that you want to move into the queue.

-Note: This low-level example performs a single write attempt. In a real-world scenario, you would typically place this logic inside a loop (similar to the try_write example) to handle cases where the queue is initially full and to ensure all data is eventually sent.
