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: df_tests.rs
    path of file: ./repos/tensorbase/crates/engine/tests
    
    the code of the file until where you have to start completion: use std::{
    collections::HashMap,
    ffi::{c_void, CString},
    fs,
    path::Path,
    ptr,
    time::Instant,
};

use base::{debug, mmap::mm_file_ro};
use engine::errs::EngineError;
use engine::errs::EngineResult;
use meta::{
    store::parts::{open_file_as_fd, CoPaInfo, PartStore},
    types::{BqlType, ColumnInfo, Id},
};

use arrow::{
    array::{ArrayData, Int32Array},
    datatypes::{Int32Type, SchemaRef},
};
use arrow::{
    array::{ArrayRef, UInt32Array},
    ffi::FFI_ArrowArray,
    record_batch
    
async fn basic_query() -> EngineResult<()> {
    let cis = vec![(CID0, BqlType::UInt(32))];
    let mut query_id = 1u64;
    let sql = "select sum(trip_id) from trips_lite";
    // let sql = "select sum(123*trip_id+456) from trips_lite where trip_id>666";
    // let sql = "select sum(trip_id) from trips_lite where trip_id>666";
    let exprs = vec!["sum(trip_id)"];
    let res_chk = vec![vec![1072792700412018895]];
    query_id += 1;
    run_ker_test_arrow(
        query_id.to_string().as_str(),
        cis,
        exprs,
        res_chk,
        None,
        sql,
    )
    .await?;

    Ok(())
