[Help/Bug] TcpConnection::write_all does not return an error when there are internet issues or a disconnected connection.

[EnvOut]

Hello everyone,

I've faced a strange problem when working with TcpConnection. Having an initialized connection using:

TcpStream::connect(pool_info.url)

even if the ethernet (Wi-Fi) is turned off, subsequent write operations do not return std::io::Error:

con.write_all(buf.as_slice()).await.unwrap();
con.flush().await.unwrap();

This seems quite strange, and I was wondering if you could suggest how to still get an io::Error if there is a problem with the connection?
