Error when checking a database version using check_db_version_file

Variants§

§

MissingFile

Unable to determine the version of the database; the file is missing.

Your database version is incompatible with the latest database version.

Fields

§version: u64

The detected version in the database.

§

IORead

IO error occurred while reading the database version file.

Fields

§err: Error

The encountered IO error.

§path: PathBuf

The path to the database version file.
