Struct FileFormatVersionNumbers 

pub struct FileFormatVersionNumbers { /* private fields */ }

File format version numbers (2 Bytes)

The file format write version and file format read version at offsets 18 and 19 are intended to allow for enhancements of the file format in future versions of Sqlite. In current versions of Sqlite, both of these values are:

• 1 for rollback journalling modes; and
• 2 for WAL journalling mode.

If a version of Sqlite coded to the current file format specification encounters a database file where the read version is 1 or 2 but the write version is greater than 2, then the database file must be treated as read-only. If a database file with a read version greater than 2 is encountered, then that database cannot be read or written.
