获取当前版本

pub fn is_applied(&self, version: u32) -> Result<bool, SqliteError>

检查迁移是否已应用

pub fn migrate( &self, migrations: &[Migration], ) -> Result<MigrationReport, SqliteError>

执行所有待执行的迁移

pub fn migrate_with<F>(&self, f: F) -> Result<MigrationReport, SqliteError>

where F: FnOnce(&mut MigrationBuilder),

使用构建器执行迁移
