Expand description

A trait for defining migrations.

Required Methods§

source

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

Runs the migration.

Errors

Returns an error if the migration fails, or if a connection to the database cannot be established.

source

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

Reverts the migration.

Errors

Returns an error if the migration fails, or if a connection to the database cannot be established.
