find the last accessed date of a directory in rust

To find the last accessed date of a directory in Rust, you can use the metadata function from the std::fs module to get metadata about the directory. The returned Metadata struct contains various information about the directory, including its last accessed time.

Here's an example code snippet that demonstrates how to get the last accessed time of a directory:

main.rs
use std::fs;

fn main() {
    let dir_path = "/path/to/directory";

    match fs::metadata(dir_path) {
        Ok(metadata) => {
            let last_accessed = metadata.accessed().unwrap();
            println!("Last accessed: {:?}", last_accessed);
        }
        Err(e) => {
            println!("Error getting metadata: {}", e);
        }
    }
}

In this example, we first specify the path to the directory that we want to retrieve the last accessed date for. We then use the metadata function to retrieve the metadata for that directory. If the metadata is successfully retrieved, we can then call the accessed method on the Metadata struct to get the SystemTime object representing the date and time the directory was last accessed. Note that accessed returns a Result<SystemTime, io::Error> and therefore we need to unwrap it to retrieve the actual date and time value.

Once we have the SystemTime object, we can print it out or use it in whatever way we need to.
