Get working dir path in Rust 1.55

In Rust 1.55, you can use the std::env::current_dir() function to get the current working directory path. Here's an example:

use std::env;
fn main() {

    // Get the current working directory path

    let current_dir = env::current_dir().unwrap();
// Print the current working directory path

    println!("Current working directory path: {:?}", current_dir);

}

This will print out something like:

Current working directory path: "/Users/username/projects/my_project"

Note that current_dir() returns a Result type, so you need to handle any errors that may occur. In this example, we're using .unwrap() to unwrap the Ok variant of the Result, which will panic if an error occurs. However, you should handle the error appropriately in a real-world application.

Also note that the returned path is an OS-specific PathBuf, which can be converted to a string using the .to_string_lossy() method. For example:

let current_dir = env::current_dir().unwrap().to_string_lossy();
println!("Current working directory path: {}", current_dir);

This will print out the same thing as the previous example.
