I am trying to debug the code below with vscode, but an error occurs.
Development environment
- Microsoft Windows 10 Home 10.0.19042 Build 19042
- rustc 1.49.0 (e1884a8e3 2020-12-29)
- Vscode 1.54.3

//arrow = "3.0.0"
//tokio = { version = "0.2", features = ["macros", "blocking", "rt-core", "rt-threaded", "sync"] }
use std::time::{Duration, Instant};
use arrow::util::pretty;
use datafusion::error::Result;
use datafusion::prelude::*;
/// This example demonstrates executing a simple query against an Arrow data source (CSV) and
/// fetching results
#[tokio::main]
async fn main() -> Result<()> {
println!("======== Start Program ========");
let start = Instant::now();
// let res_path = r"/root/workspace/project/hello_arrow/res/sample_01.csv";
// http://insideairbnb.com/get-the-data.html

let res_path = r"D:\workspace\vscode\arrow_rust\res\review.01.csv";
// create local execution context
let mut ctx = ExecutionContext::new();
// register csv file with the execution context
ctx.register_csv("datatable_01", res_path, CsvReadOptions::new())?;
// execute the query
let sql = "SELECT count(id) from datatable_01";
let df = ctx.sql(sql)?;
let results = df.collect().await?;
// print the results
pretty::print_batches(&results)?;
let duration = start.elapsed();
println!("Time elapsed in expensive_function() is: {:?}", duration);
println!("======== End Program ========");
Ok(())
}

The program runs normally. Debugging fine on Linux for the same code.
Is there any other way to debug on Windows?
