|
| -// To use, simply construct a QuicDataReader using the underlying buffer that
|
| -// you'd like to read fields from, then call one of the Read*() methods to
|
| -// actually do some reading.
|

|

|
| -// read and each successive Read*() call automatically increments said iterator
|
| -// on success. On failure, internal state of the QuicDataReader should not be
|
| -// trusted and it is up to the caller to throw away the failed instance and
|
| -// handle the error as appropriate. None of the Read*() methods should ever be
|
| -// called after failure, as they will also fail immediately.
