Trait Implementations§

Source§

impl Migration for CreateLedgerTables

Source§

fn name(&self) -> &'static str

Source§

fn up<'a>( &'a self, schema: &'a Schema<'a>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'a>>

Apply the change.
Source§

fn down<'a>( &'a self, schema: &'a Schema<'a>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'a>>

Undo it. A migration that cannot be undone should say so by returning an error, rather than silently doing nothing.
