find the last accessed date of a json file in rust

To find the last accessed date of a file, we need to access its metadata. We can use the std::fs::metadata function to retrieve metadata for a given file. Here's an example code snippet:

main.rs
use std::fs;

fn main() -> std::io::Result<()> {
    let file_path = "path/to/your/file.json";
    let metadata = fs::metadata(file_path)?;
    let last_accessed = metadata.accessed()?;

    println!("Last accessed: {:?}", last_accessed);

    Ok(())
}
253 chars
12 lines

In this code, we first define the path to the JSON file as a string. We then use the fs::metadata function to retrieve the std::fs::Metadata object for this file. Finally, we use the accessed method of the Metadata object to retrieve the SystemTime when the file was last accessed.

Note that we have used the ? operator to propagate any potential errors up the call stack.
