pub trait FileTypeExt {

}
Unix-specific extensions for fs::FileType.
Adds support for special Unix file types such as block/character devices, pipes, and sockets.
fn is_block_device(&self) -> boolReturns true if this file type is a block device.

let file_type = meta.file_type();
assert!(file_type.is_block_device());
Ok(())
}fn is_char_device(&self) -> boolReturns true if this file type is a char device.

fn main() -> io::Result<()> {

Ok(())
}fn is_fifo(&self) -> boolReturns true if this file type is a fifo.

}fn is_socket(&self) -> boolReturns true if this file type is a socket.
