Trait std::os::unix::fs::FileTypeExt

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

Add support for special unix types (block/char device, fifo and socket).

Required Methods

This is supported on Unix only.

Returns whether this file type is a block device.

Examples

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

let meta = fs::metadata("block_device_file")?;
let file_type = meta.file_type();
assert!(file_type.is_block_device());

This is supported on Unix only.

Returns whether this file type is a char device.

Examples

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

let meta = fs::metadata("char_device_file")?;
let file_type = meta.file_type();
assert!(file_type.is_char_device());

This is supported on Unix only.

Returns whether this file type is a fifo.

Examples

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

let meta = fs::metadata("fifo_file")?;
let file_type = meta.file_type();
assert!(file_type.is_fifo());

This is supported on Unix only.

Returns whether this file type is a socket.

Examples

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

let meta = fs::metadata("unix.socket")?;
let file_type = meta.file_type();
assert!(file_type.is_socket());
