find the last modified date of a file in rust

To find the last modified date of a file in Rust, we can use the metadata method from the std::fs module.

Here's an example code snippet that demonstrates how to do this:

main.rs
use std::fs;

fn main() {
    let file_path = "/path/to/file.txt";

    match fs::metadata(file_path) {
        Ok(metadata) => {
            let modified = metadata.modified().unwrap();
            println!("Last modified date: {:?}", modified);
        }
        Err(error) => {
            eprintln!("Error getting metadata for file {}: {}", file_path, error);
        }
    }
}

In this code, we first provide the path to the file whose last modified date we want to find. We then call the metadata method on the file path, which returns a Result value.

If metadata returns an Ok value, we can then call the modified method on the metadata to get the SystemTime timestamp representing the last modified date of the file.

Finally, we print the last modified date using println!. If metadata returns an Err value, we handle the error by printing an error message using eprintln!.
