Struct metrics_util::MetricKindMask

pub struct MetricKindMask(_);

Metric kind mask.

Useful for matching against a kind, or kinds, of metrics.

In order to use for defining multiple metric kinds, can be used in a bitmask fashion, as this type implements bitwise OR support, and checking for inclusion of a specific kind within another kind value can be checked via matches:

// Let's only match counters and histograms:
let mask = MetricKindMask::COUNTER | MetricKindMask::HISTOGRAM;

// And check to see if the kinds we have matches our mask:
assert!(!mask.matches(MetricKind::Gauge));
assert!(mask.matches(MetricKind::Counter));

// There's even two handy versions to avoid extra typing:
let none_mask = MetricKindMask::NONE;
let all_mask = MetricKindMask::ALL;

assert!(!none_mask.matches(MetricKind::Counter));
assert!(!none_mask.matches(MetricKind::Gauge));
assert!(!none_mask.matches(MetricKind::Histogram));
assert!(all_mask.matches(MetricKind::Counter));
assert!(all_mask.matches(MetricKind::Gauge));
assert!(all_mask.matches(MetricKind::Histogram));

Implementations
