This is supported on Unix only.

.
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.
