    Ok(())
}Run

This is supported on Unix only.

Returns the time of the last modification of the file.

Examples

use std::fs;
use std::os::unix::fs::MetadataExt;
use std::io;

fn main() -> io::Result<()> {
    let meta = fs::metadata("some_file")?;
    let last_modification_time = meta.mtime();
    Ok(())
}Run

This is supported on Unix only.

Returns the time of the last modification of the file in nanoseconds.

Examples

use std::fs;
use std::os::unix::fs::MetadataExt;
use std::io;

fn main() -> io::Result<()> {
    let meta = fs::metadata("some_file")?;
    let nano_last_modification_time = meta.mtime_nsec();
    Ok(())
}Run

This is supported on Unix only.

Returns the time of the last status change of the file.

Examples

use std::fs;
use std::os::unix::fs::MetadataExt;
use std::io;

fn main() -> io::Result<()> {
    let meta = fs::metadata("some_file")?;
