func Scan ¶

func Scan(r io.Reader) (Result, error)

Scan scans the given reader, which should contain Protobuf source, and returns the set of imports declared in the file. The result also contains the value of any package declaration in the file. It returns an error if there is an I/O error reading from r. In the event of such an error, it will still return a result that contains as much information as was found before the I/O error occurred.
