Struct MeasurementSummary 

pub struct MeasurementSummary { /* private fields */ }

Saturating aggregate for one instruction measurement role.

Sample count and total saturate independently at u64::MAX. Treat that value as unavailable for exact interval arithmetic, including when it was reached exactly. Latest and maximum remain observations, not cumulative counters. Aggregates reset when the registration identity changes.

Implementations

impl MeasurementSummary

pub const fn samples(self) -> u64

Return the number of completed samples.

Return the saturating sum of all samples.

pub const fn latest(self) -> Option<u64>

Return the latest sample, if one exists.

pub const fn maximum(self) -> Option<u64>

Return the largest sample, if one exists.
