Enum controlgroup::DeviceNumber

pub enum DeviceNumber {
    Any,
    Number(u16),
}

Device major/minor number.

DeviceNumber implements FromStr and Display. You can convert a string into a DeviceNumber and vice versa. parse returns an error with kind ErrorKind::Parse if failed.

use controlgroup::DeviceNumber;

let n = "8".parse::<DeviceNumber>().unwrap();
assert_eq!(n, DeviceNumber::Number(8));

let n = "*".parse::<DeviceNumber>().unwrap();
assert_eq!(n, DeviceNumber::Any);

use controlgroup::DeviceNumber;

assert_eq!(DeviceNumber::Number(8).to_string(), "8");
assert_eq!(DeviceNumber::Any.to_string(), "*");

DeviceNumber also implements From<u16>, which results in DeviceNumber::Number.

use controlgroup::DeviceNumber;

assert_eq!(DeviceNumber::from(8), DeviceNumber::Number(8));

Variants

Any

Any number matches.

Number(u16)

Specific number.
