Например, чтобы указать значение метаданных `title` для path-параметра `item_id`, вы можете написать:

    ```Python hl_lines="11"

	t.mu.RLock()
	defer t.mu.RUnlock()

	if t.requestsPool == nil {

 *  Fix: When closing a canceled HTTP/2 stream, don't send the `END_STREAM` flag. This could cause
    the server to incorrectly interpret the stream as having completed normally. This is most useful
    when a request body needs to cancel its own call.
