The migration definition

Required Methods

fn up<'life0, 'life1, 'async_trait>( &'life0 self, manager: &'life1 SchemaManager<'_>, ) -> Pin<Box<dyn Future<Output = Result<(), DbErr>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Define actions to perform when applying the migration

Provided Methods

fn down<'life0, 'life1, 'async_trait>( &'life0 self, _manager: &'life1 SchemaManager<'_>, ) -> Pin<Box<dyn Future<Output = Result<(), DbErr>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Define actions to perform when rolling back the migration
