title: when asyncio.StreamReader.read() called, which type of Error occur?
body: <p>Now I make TCP server with asyncio.</p>
  
  <p>I want added exception error handling in my code. (like below)</p>
  
  <pre><code>    try:
          data = await reader.read(SERVER_IO_BUFFER_SIZE)
      except SomeError:
          #error handle
  </code></pre>
  
  <p>So, I look asyncio official document.</p>
  
  <p>but I can't find any of information about Errors that may occur.</p>
  
  <p>(link: <a href="https://docs.python.org/3/library/asyncio-stream.html#asyncio.StreamReader.read" rel="nofollow noreferrer">https://docs.python.org/3/library/asyncio-stream.html#asyncio.StreamReader.read</a>)</p>
  
  <p>How can I get infomation about Errors that may occur?</p>
