Struct SqlitePersistenceProvider 

pub struct SqlitePersistenceProvider { /* private fields */ }

SQLite-backed persistence provider for the WFE workflow engine.

Implementations

impl SqlitePersistenceProvider

pub async fn new(database_url: &str) -> Result<Self, Box<dyn Error>>

Create a new provider connected to the given SQLite database URL.

For in-memory databases, pass ":memory:". The schema tables are created automatically.
