Function ensure_schema 

pub async fn ensure_schema(
    pool: &SqlitePool,
    table_name: &str,
) -> Result<(), OutboxError>

Apply the canonical SQLite outbox schema to the target database.

Intended for POCs, integration tests and local development. Production deployments should run their own migration tooling against the SQL rendered by Dialect::schema_ddl.

Errors

• OutboxError::Internal if table_name is not a valid identifier.
• OutboxError::Database if the connection or the DDL statement fails.
