Struct DurationSummary 

Source 
#[non_exhaustive]
pub struct DurationSummary {
    pub sample_count: u64,
    pub average_ms: Option<u64>,
    pub p50_ms: Option<u64>,
    pub p90_ms: Option<u64>,
    pub p95_ms: Option<u64>,
    pub p99_ms: Option<u64>,
}
Expand description

Aggregate wall-clock durations for a population of test samples.

Metrics are None when the population is empty so a serialized summary distinguishes “not measured” from an observed zero-millisecond duration.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§sample_count: u64

Number of measured samples.

§average_ms: Option<u64>

Integer mean, or None when there are no samples.

§p50_ms: Option<u64>

Median sample using the pinned test-runner percentile convention.

§p90_ms: Option<u64>

90th-percentile sample.

§p95_ms: Option<u64>

95th-percentile sample.

§p99_ms: Option<u64>

99th-percentile sample.
