The Info trait provides database-agnostic methods for managing migrations and interacting with migration states.

Required Methods

fn migrations(&self) -> &Vec<Box<dyn Migration<DB>>>

Returns a reference to the list of migrations.

fn migrations_mut(&mut self) -> &mut Vec<Box<dyn Migration<DB>>>

Returns a mutable reference to the list of migrations.

Provided Methods

fn add_migrations( &mut self, migrations: Vec<Box<dyn Migration<DB>>>, ) -> Result<(), Error>

Adds a list of migrations to the migrator.

This method accepts a vector of migrations and adds each one individually to ensure proper handling of migration relationships and duplicates.

Errors

If migration is added with same app and name but inconsistent value i.e its parents, run before, replaces and is atomic differ and do not have same number of operation

fn add_migration( &mut self, migration: Box<dyn Migration<DB>>, ) -> Result<(), Error>

Adds a single migration to the migrator.

Errors

If migration is added with same app and name but inconsistent value i.e its parents, run before, replaces and is atomic differ and do not have same number of operation
