#[non_exhaustive]
pub enum MetricSnapshot {
    Counter {
        name: String,
        value: u64,
    },
    Gauge {
        name: String,
        value: i64,
    },

    },
}

A snapshot of a single metric.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Counter

A counter metric (monotonically increasing).

Fields

name: String

Metric name.

value: u64

Current value.

Gauge

A gauge metric (can go up or down).

Fields

name: String

Metric name.

value: i64

Current value.

Histogram

A histogram metric (distribution).

Fields

name: String

Metric name.

buckets: Vec<(f64, u64)>

Bucket boundaries and cumulative counts.

sum: f64

Sum of all values.

count: u64

Total count of values.
