fn is_char_device(&self) -> bool;
fn is_fifo(&self) -> bool;
fn is_socket(&self) -> bool; }
This is supported on Unix only.

Unix-specific extensions for FileType.

Adds support for special Unix file types such as block/character devices, pipes, and sockets.

Required methods

fn is_block_device(&self) -> bool

This is supported on Unix only.

Returns true if this file type is a block device.

Examples

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

fn main() -> io::Result<()> {
    let meta = fs::metadata("block_device_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_block_device());
    Ok(())
}
Run

fn is_char_device(&self) -> bool

This is supported on Unix only.

Returns true if this file type is a char device.

Examples

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

fn main() -> io::Result<()> {
    let meta = fs::metadata("char_device_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_char_device());
    Ok(())
}
Run

fn is_fifo(&self) -> bool

This is supported on Unix only.

Returns true if this file type is a fifo.

Examples

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

fn main() -> io::Result<()> {
    let meta = fs::metadata("fifo_file")?;
    let file_type = meta.file_type();
    assert!(file_type.is_fifo());
    Ok(())
}
Run

fn is_socket(&self) -> bool

This is supported on Unix only.

Returns true if this file type is a socket.

Examples

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

fn main() -> io::Result<()> {
    let meta = fs::metadata("unix.socket")?;
    let file_type = meta.file_type();
    assert!(file_type.is_socket());
    Ok(())
}
