Required Methods

fn up<'life0, 'async_trait>(
    &'life0 self,
    env: Env
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Runs a migration.

fn get_id(&self) -> &str

A status about a migration will be stored in a db collection with the following document id

Provided Methods

fn down<'life0, 'async_trait>(
    &'life0 self,
    _env: Env
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Rollbacks a migration. Since not every migration could be rollbacked and it often happens there is a blank implementation
