Enum controlgroup::Max

pub enum Max {
    Max,
    Limit(u32),
}

Limits the maximum number or amount of a resource, or not limits.

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

use controlgroup::Max;

let max = "max".parse::<Max>().unwrap();
assert_eq!(max, Max::Max);

let num = "42".parse::<Max>().unwrap();
assert_eq!(num, Max::Limit(42));

assert_eq!(Max::Max.to_string(), "max");
assert_eq!(Max::Limit(42).to_string(), "42");

Max also implements Default, which yields Max::Max.

use controlgroup::Max;

assert_eq!(Max::default(), Max::Max);

Variants
