ConnReadN reads at most N bytes from reader and it optimized for connection based readers like net.Conn it should not be used for file/buffer based reading, ConnReadN should be preferred instead of 'conn.Read() without loop' .

ConnReadNWithTimeout is same as ConnReadN but it takes timeout instead of context and it returns error if read does not finish in given time.

IsAcceptedError checks if the error is accepted error for example: connection refused, io.EOF, io.ErrUnexpectedEOF while reading from connection.
