You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: store.rs
    path of file: ./repos/dust/core/src/databases_store
    
    the code of the file until where you have to start completion: use anyhow::Result;
use async_trait::async_trait;
use bb8::Pool;
use bb8_postgres::PostgresConnectionManager;
use serde_jso
    
    async fn init(&self) -> Result<()> {
        let conn = self.pool.get().await?;
        for table in POSTGRES_TABLES {
            conn.execute(table, &[]).await?;
        }
        for index in SQL_INDEXES {
            conn.execute(index, &[]).await?;
        }
        Ok(())
    }
