Implementations

impl Migrator

pub fn migrate_lmdb_to_safe_mode<S, D>(
    src_env: S,
    dst_env: D
) -> Result<(), MigrateError> where
    S: Deref<Target = Rkv<LmdbEnvironment>>,
    D: Deref<Target = Rkv<SafeModeEnvironment>>, 

Migrate all data in all of databases from the source environment to the destination environment. This includes all key/value pairs in the main database that aren't metadata about subdatabases and all key/value pairs in all subdatabases.

Other backend-specific metadata such as map size or maximum databases left intact on the given environments.

The destination environment should be empty of data, otherwise an error is returned.

pub fn auto_migrate_lmdb_to_safe_mode<F, D>(
    path: &Path,
    build: F,
    dst_env: D
) -> Result<(), MigrateError> where
    F: FnOnce(Lmdb) -> Lmdb,
    D: Deref<Target = Rkv<SafeModeEnvironment>>, 

Same as the other migration methods, but automatically attempts to open the source environment, ignores it if it doesn't exist or if it's empty, and finally attempts to delete all of its supporting files.
