Struct for running migrations on a database

Implementations§

Source§

impl<S, M, E> MigrationRunner<S, M, E>

Source

pub fn new(store: S, state_manager: Arc<M>, executor: Arc<E>) -> Self

Create a new MigrationRunner

Source

pub async fn migrate(&self) -> Result<Option<u32>>

Migrate with a separate transaction for each changelog

This will execute each migration inside its own DB transaction. Therefore, if an error occurs and the method returns prematurely, all versions that have been successfully deployed will stay in the database.
