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: arrow_ipc_file.rs
    path of file: ./repos/roapi/columnq/src/table
    
    the code of the file until where you have to start completion: use std::sync::Arc;

use datafusion::arrow;
use datafusion::arrow::datatypes::Schema;
use datafusion::arrow::record_batch::RecordBatch;
use log::debug;
use snafu::prelude::*;

use crate::table::{self, TableSource};

#[derive(Debug, Snafu)]
pub enum Error {
    #[snafu(display("Faild to create IPC file reader: {source}"))]
    NewReader {
        source: datafusi
    
    async fn load_file() {
        let ctx = SessionContext::new();
        let test_path = test_data_path("uk_cities_with_headers.arrow");

        let t = to_mem_table(&TableSource::new("uk_cities".to_string(), test_path), &ctx)
            .await
            .unwrap();

        let stats = t
            .scan(&ctx.state(), None, &[], None)
            .await
            .unwrap()
            .statistics();
        assert_eq!(stats.num_rows, Some(37));
    }
