Struct Rule 

pub struct Rule {
    pub metric: MetricId,
    pub op: Op,
    pub value: f64,
}

A metric threshold: the target passes the rule when metric op value.

Fields

metric: MetricId

op: Op

value: f64

Implementations

impl Rule

pub fn parse(text: &str) -> Result<Rule, String>

Parses <metric> <op> <value>, for example holders >= 1000. The spaces are optional.

pub fn eval(&self, value: Option<f64>) -> RuleStatus

Judges value against the rule. No value is an error: health is unknown, never a pass.
