Enum ZoneMigrationError 

pub enum ZoneMigrationError {
    MissingStore(PathBuf),
    NotALegacyStore(PathBuf),

    HeaderUnrecoverable(PathBuf),
    Io(Error),
}

Variants

MissingStore(PathBuf)

The data file does not exist.

NotALegacyStore(PathBuf)

AlreadyZoned(PathBuf)

The store is already zoned (a valid superblock zone is present).

HeaderUnrecoverable(PathBuf)

No usable database header survives in page 0 or the rdb-hdr shadow.

Io(Error)
