Required Methods

Deprecated since 1.8.0

: deprecated in favor of the accessor methods of this trait

This is supported on Linux only.

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.

Examples

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

This is supported on Linux only.

Returns the device ID on which this file resides.

Examples

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

This is supported on Linux only.

Returns the inode number.

Examples

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

This is supported on Linux only.

Returns the file type and mode.

Examples

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
This is supported on Linux only.

Returns the number of hard links to file.

Examples

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

This is supported on Linux only.

Returns the user ID of the file owner.

Examples

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

This is supported on Linux only.

Returns the group ID of the file owner.

Examples

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());
    Ok(())
}Run

This is supported on Linux only.

Returns the device ID that this file represents. Only relevant for special file.

Examples

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

This is supported on Linux only.

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.

Examples

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(())
}Run

This is supported on Linux only.

Returns the last access time.

Examples

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

This is supported on Linux only.

Returns the last access time, nano seconds part.

Examples

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

This is supported on Linux only.

Returns the last modification time.

Examples

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());
    Ok(())
}Run

This is supported on Linux only.

Returns the last modification time, nano seconds part.

Examples

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_nsec());
    Ok(())
}Run

This is supported on Linux only.

Returns the last status change time.

Examples

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());
    Ok(())
}Run

This is supported on Linux only.

Returns the last status change time, nano seconds part.

Examples

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

This is supported on Linux only.

Returns the "preferred" blocksize for efficient filesystem I/O.

Examples

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());
    Ok(())
}Run

This is supported on Linux only.

Returns the number of blocks allocated to the file, 512-byte units.

Examples

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_blocks());
    Ok(())
}Run
