Struct forest_filecoin::db::migration::db_migration::DbMigration
source · pub struct DbMigration {
config: Config,
}
Expand description
Governs the database migration process. This is the entry point for the migration process.
Fields§
§config: Config
Forest configuration used.
Implementations§
source§impl DbMigration
impl DbMigration
pub fn new(config: &Config) -> Self
pub fn chain_data_path(&self) -> PathBuf
sourcepub fn is_migration_required(&self) -> Result<bool>
pub fn is_migration_required(&self) -> Result<bool>
Verifies if a migration is needed for the current Forest process.
Note that migration can possibly happen only if the DB is in current
mode.
sourcepub fn migrate(&self) -> Result<()>
pub fn migrate(&self) -> Result<()>
Performs a database migration if required. Note that this may take a long time to complete and may need a lot of disk space (at least twice the size of the current database). On a successful migration, the current database will be removed and the new database will be used. This method is tested via integration tests.
