) -> Result<usize, DeserializeError>
Expand description

Reads a NUL terminated label starting at the beginning of the given slice.

If a NUL terminated label could not be found, then an error is returned. Similarly, if a label is found but doesn’t match the expected label, then an error is returned.

Upon success, the total number of bytes read (including padding bytes) is returned.
