get the temp directory rust

To get the temporary directory in Rust, you can use the tempdir crate. First, add tempdir to your dependencies in your Cargo.toml file:

[dependencies]
tempdir = "0.3"

Then, you can use the following code to create a temporary directory:

use std::env;
use std::path::PathBuf;
use tempdir::TempDir;

fn main() {
    let temp_dir = TempDir::new("my_temp_dir").expect("Failed to create temporary directory");

    let path_buf: PathBuf = temp_dir.into();
    let path = path_buf.to_str().expect("Failed to convert path to string");

    println!("Temporary directory: {}", path);
}

This code creates a temporary directory using TempDir::new and assigns it to the temp_dir variable. Then, it converts the TempDir into a PathBuf using into(). Finally, it converts the PathBuf into a string using to_str() and prints the path to the console.

Make sure to handle any errors that may occur during the creation of the temporary directory.
