other methods of this trait are now preferred
Gain a reference to the underlying stat
structure which contains
the raw information returned by the OS.
The contents of the returned stat
are not consistent across
Unix platforms. The os::unix::fs::MetadataExt
trait contains the
cross-Unix abstractions contained within the raw stat.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
let stat = meta.as_raw_stat();
Ok(())
}
Run
Returns the device ID on which this file resides.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_dev());
Ok(())
}
Run
Returns the inode number.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_ino());
Ok(())
}
Run
Returns the file type and mode.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_mode());
Ok(())
}
Run
Returns the number of hard links to file.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_nlink());
Ok(())
}
Run
Returns the user ID of the file owner.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_uid());
Ok(())
}
Run
Returns the group ID of the file owner.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_gid());

}
Run
Returns the device ID that this file represents. Only relevant for special file.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_rdev());
Ok(())
}
Run
Returns the size of the file (if it is a regular file or a symbolic link) in bytes.
The size of a symbolic link is the length of the pathname it contains,
without a terminating null byte.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_size());
Ok(())
}

use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_atime());
Ok(())
}
Run
Returns the last access time of the file, in nanoseconds since st_atime
.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_atime_nsec());
Ok(())
}
Run
Returns the last modification time of the file, in seconds since Unix Epoch.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_mtime());

.

use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_mtime_nsec());
Ok(())
}
Run

use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_ctime());

.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_ctime_nsec());
Ok(())
}
Run
Returns the “preferred” block size for efficient filesystem I/O.
use std::fs;
use std::io;
use std::os::linux::fs::MetadataExt;
fn main() -> io::Result<()> {
let meta = fs::metadata("some_file")?;
println!("{}", meta.st_blksize());

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