Trait Synchronize

pub trait Synchronize<DB>: Info<DB> + DatabaseOperation<DB>
where
    DB: Database,
{
    // Provided method
    fn sync<'life0, 'life1, 'life2, 'async_trait, O>(
        &'life0 self,
        connection: &'life1 mut <DB as Database>::Connection,
        old_migrator: &'life2 O,
    ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
       where O: OldMigrator<DB> + 'async_trait,
             Self: Sync + 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait { ... }
}

Trait which is implemented by a migrator which supports synchronization from old migrator to new migrator

Provided Methods

fn sync<'life0, 'life1, 'life2, 'async_trait, O>( &'life0 self, connection: &'life1 mut <DB as Database>::Connection, old_migrator: &'life2 O, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where O: OldMigrator<DB> + 'async_trait, Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Synchronizes migrations from an older migration system to the sqlx migrator.

This function serves two primary purposes:

1. Migrating from external migrations tosqlx_migrator migration
2. Handling table renames

Note: Migration timestamps are not preserved - the current time is used for entries

Errors

If sync cannot be completed

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
