Struct TimeStats 

pub struct TimeStats {
    pub count: u64,
    pub total_ns: i128,
    pub min_ns: Option<i128>,
    pub max_ns: Option<i128>,
    pub mean_ns: f64,
    pub median_ns: Option<f64>,
    pub variance_ns2: f64,
}

Summary statistics for timing values.

All fields use nanoseconds except variance_ns2, which is nanoseconds squared. Values may represent signed timing quantities such as scheduling error or one-way delay.

Fields

count: u64

Number of samples included in this summary.

total_ns: i128

Sum of all samples, in nanoseconds.

min_ns: Option<i128>

Smallest sample, in nanoseconds.

max_ns: Option<i128>

Largest sample, in nanoseconds.

mean_ns: f64

Arithmetic mean, in nanoseconds.

median_ns: Option<f64>

Median, in nanoseconds, when exact samples were retained.

variance_ns2: f64

Sample variance, in nanoseconds squared.

Implementations

impl TimeStats

pub fn stddev_ns(&self) -> f64

Returns the sample standard deviation, in nanoseconds.

pub fn is_empty(&self) -> bool

Returns whether this summary contains no samples.

Trait Implementations

impl Clone for TimeStats

fn clone(&self) -> TimeStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TimeStats

impl Debug for TimeStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TimeStats

fn eq(&self, other: &TimeStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
