find the path of a csv file in rust

To find the path of a CSV file in Rust, you can use the std::path::PathBuf datatype and the std::env::current_dir() function. First, create a PathBuf variable and initialize it with the name of your file:

main.rs
use std::path::PathBuf;

let file_name = "my_file.csv";
let mut path = PathBuf::new();
path.push(file_name);

This code creates a PathBuf object and appends the file name to it. Now, you can use the current_dir() function to get the current working directory (the directory from which your Rust code is being executed), and join it with the PathBuf object using the join function:

main.rs
use std::env;

let current_dir = env::current_dir().expect("Failed to get current directory");
path = current_dir.join(path);

The current_dir() function returns a Result object, which is why we use the expect() function to handle any possible errors. Finally, your path variable will contain the full path to your CSV file, and you can use it to open, read, write or manipulate the file using Rust's CSV and file I/O libraries.
